Classification of matter
Chemists classify matter as either pure substances or mixtures. Pure substances have a definite composition and include elements and compounds. Mixtures contain two or more substances mixed together, each retaining their own properties, and can be either homogeneous, with an even distribution of components, or heterogeneous, with an uneven distribution where the parts can be seen. Compounds are pure substances made of two or more elements chemically bonded together.
Unit 2 Properties of Matter
This document provides an overview of properties of matter. It begins by defining the three states of matter - solids, liquids, and gases. It describes the properties of each state, such as solids having a fixed shape and volume while gases have no fixed shape or volume.

Lecture 2.1- Properties of Matter
This document discusses the properties and states of matter, describing extensive and intensive properties, and how matter can exist as solids, liquids, or gases depending on how tightly or loosely packed the particles are. Key topics covered include classifying properties as extensive or intensive based on whether they depend on amount of matter, identifying substances based on uniform composition and properties, and explaining the defining characteristics of solids, liquids, and gases in terms of particle motion and arrangement.
Chapter 2 notes properties of matter
Everything can be categorized as either energy or matter. There are two types of properties that characterize matter: physical properties, which can be observed without changing the substance, and chemical properties, which are observed when a substance changes. A physical change alters a substance's size, shape, or form but not its composition, while a chemical change creates a new substance with different properties. The law of conservation of matter states that matter is neither created nor destroyed in physical and chemical changes.
Honor Chemistry 2
This document provides an overview of key chemistry concepts including:
1) A substance has a uniform and definite composition, while a mixture's composition can vary. Substances are identified by their intensive properties.
2) Matter exists in solid, liquid, and gas states depending on how tightly or loosely particles are packed. Physical changes alter properties but not composition.
3) A chemical change produces new substances with different compositions through rearrangement of atoms. Chemical properties and reactions allow identification of substances.
4) Chemical formulas and symbols represent the composition of compounds and elements. The subscripts in formulas indicate the relative proportions of elements in a compound.
Classification of matter
This document describes an activity to classify different types of matter as either pure substances or mixtures. Pure substances are uniformly composed throughout and can be elements or compounds. Mixtures contain two or more substances and can be either homogeneous, meaning their composition is uniform, or heterogeneous, meaning their composition varies. The activity involves examining 10 different vials of matter and classifying the contents of each as a pure substance or mixture, and if a mixture, whether it is homogeneous or heterogeneous. A table is to be completed with the classification and a reason for each vial.
Classifications of Matter
This document defines the classification of matter. There are two main categories: pure substances and mixtures. Pure substances include elements, which are made of only one type of atom, and compounds, which are two or more elements chemically bonded together. Mixtures contain two or more pure substances mixed together without chemical bonding. Mixtures can be either heterogeneous, where the parts can be seen, or homogeneous, where the parts cannot be seen. Heterogeneous mixtures are less pure than homogeneous mixtures.

CLASSIFICATION OF MATTER
The document discusses key concepts related to states of matter, mixtures, and solutions. It defines elements and compounds, and describes homogeneous and heterogeneous mixtures. Solutions are defined as homogeneous mixtures where one substance dissolves in another. Suspensions are mixtures where an insoluble material is mixed with a liquid. Solubility depends on temperature and molecular structure. The pH scale measures the concentration of hydronium and hydroxide ions to indicate if something is acidic or basic, with values below 7 being acidic and above 7 being basic.
The properties of matter
This document discusses volume, mass, density, and physical and chemical properties of matter. It provides definitions and examples of:
- Volume is measured by looking at the bottom of the meniscus of liquids.
- Mass is the amount of matter in an object and is constant anywhere, while weight depends on gravity.
- Density describes how compact a substance is and can be used to identify substances and determine if objects float or sink.
- Physical properties like state and solubility can change without changing the identity of the matter. Chemical properties involve chemical reactions that form new substances.
5 1.1 Matter Powerpoint Part A Classification Of Matter
The document provides an overview of classifying and studying matter. It defines matter as anything having mass and volume. It discusses the basic units of matter being atoms and classifies matter as either pure substances (elements or compounds) or mixtures. Elements contain only one type of atom, while compounds are made of two or more different elements that are chemically combined. Mixtures are combinations of substances that are not chemically combined and can be separated physically. Mixtures are either homogeneous, appearing uniform throughout, or heterogeneous, visibly different throughout. Examples and diagrams are provided to illustrate these key concepts.
Matter and its properties
This document discusses the fundamental properties and classification of matter. It defines matter as anything that has mass and takes up space, and it is made of atoms which combine to form elements or compounds. The properties of matter can be extensive, depending on amount, or intensive, not depending on amount. Matter exists in solid, liquid, gas and plasma states and undergoes physical changes that do not alter its chemical identity or chemical changes that create new substances. Mixtures are combinations of substances that retain their own properties, while pure substances have consistent composition and properties regardless of sample.
Classification of matter
The document discusses the classification of matter into pure substances and mixtures. Pure substances are either elements or compounds, both of which have a uniform composition. Mixtures contain two or more substances mixed together, and can be either homogeneous, with a uniform composition throughout, or heterogeneous, with a non-uniform composition. Common examples of pure substances and mixtures are provided.

Describing matter powerpoint
Matter can exist in three states - solid, liquid, and gas. Examples of solids are ice and diamonds; examples of liquids are water and mercury. Gases include water vapor and oxygen. Characteristic properties like boiling point and melting point are used to identify substances and do not change, even if the substance changes state. Physical changes alter the substance's form through processes like melting or crushing, but do not change its chemical makeup. Chemical changes form new substances through chemical reactions.
Matter and its Properties
Chemistry is the science that studies the properties of matter and how matter interacts, combines and changes. There are several branches of chemistry including organic, inorganic, biochemistry, analytical, physical, agrochemistry, astrochemistry, electrochemistry, geochemistry and environmental chemistry. Matter exists in three phases - solid, liquid, and gas. The particulate theory of matter states that all matter is made of very small particles called atoms. Properties of matter can be physical, describing characteristics that don't change its identity, or chemical, describing how it reacts with other substances. Properties can also be either intensive, independent of amount, or extensive, dependent on amount.
Classification of matter
This document discusses the classification of matter. It defines mixtures as combinations of two or more substances that are not chemically bonded and can be separated by mechanical means. Mixtures can be heterogeneous, with visible components, or homogeneous, appearing uniform. Pure substances cannot be broken down and include elements, which cannot be broken down further, and compounds, made of two or more elements joined in a fixed ratio. Elements are found on the periodic table and compounds are named according to the elements present and their ratios. The properties of materials, such as their conductivity, magnetism, and position on the periodic table, determine whether they are classified as metals, nonmetals, or metalloids.
Presentacion tema 4
Everything is made of matter, which has mass and volume. Matter exists in three states - solid, liquid, and gas. It can be natural or man-made. Atoms are the smallest particles of matter and molecules are formed when two or more atoms join together. Materials have different properties depending on how hard, soft, flexible, or breakable they are. Thermal conductors allow heat to pass through easily while insulators do not. Mixtures are two substances mixed together, either heterogeneously where the separate substances can be seen or homogeneously as a solution where the substances mix at a molecular level. Changes in matter can be physical, involving changes in shape, place or state, or chemical, forming new molecules
Describing matter
This document defines key terms related to matter: matter is anything that has mass and takes up space. A pure substance has a specific, unchanging makeup like salt or sugar. Matter has physical properties that can be observed without changing its substance, like melting point, and chemical properties that describe its ability to change into other substances through reactions. Elements are pure substances that cannot be broken down further, while mixtures contain two or more substances that are not chemically combined. Mixtures can be homogeneous, where the parts are evenly mixed and not visible, or heterogeneous, where the different parts can be seen.

This document defines and describes the basic properties and types of matter. It discusses the building blocks of matter including atoms, elements, and compounds. It also defines extensive and intensive properties, and the three common states of matter - solid, liquid, and gas. Additionally, it distinguishes between physical and chemical properties, and physical and chemical changes. It describes mixtures and pure substances, and provides examples of classifying different types of matter.
The nature of matter
The document discusses the nature of matter. It describes matter as being composed of tiny particles called atoms that can be arranged into elements or compounds. Matter exists in three states - solid, liquid, and gas - which are distinguished by how tightly or loosely packed the particles are and how freely they can move. Mixtures are substances made of two or more materials mixed together, while pure substances have a consistent composition and can be either elements or compounds. The document outlines several methods for separating mixtures, including filtration, distillation, centrifugation, and chromatography.
Matter and materials
1. The document discusses various properties of matter and how they are used to classify and identify different types of matter. It describes extensive properties that depend on amount and intensive properties that depend on type.
2. Mixtures and pure substances are introduced. Heterogeneous mixtures are non-uniform while homogeneous mixtures are uniform throughout. Elements have a unique set of properties while compounds contain two or more elements.
3. The three states of matter are defined as solid, liquid, and gas. Physical and chemical changes are distinguished based on whether the composition changes. Chemical symbols and formulas are used to represent elements and compounds in chemical reactions.
8th; chapter 2; the nature of matter
This chapter discusses the nature of matter. It describes matter and the different types including elements, compounds, mixtures, and changes in matter. It also discusses energy and how energy changes occur during physical and chemical changes to matter.

Science chapter 2!
This document discusses matter and its properties. It defines matter as either pure substances or mixtures. Pure substances are either elements or compounds, while mixtures can be homogeneous or heterogeneous. The document then discusses several physical properties of matter like viscosity, conductivity, malleability, hardness, density, melting point, and boiling point. It explains processes like distillation, filtration, evaporation, and electrolysis that are used to separate mixtures based on these physical properties. The review questions ask about examples of physical changes, classifying mixtures, why mixtures vary, and separation processes.
Science party
There are currently 118 known elements that make up all matter. Elements are pure substances that contain only one type of atom, while compounds are made of two or more elements or other compounds. Mixtures have a variable composition because their ingredients are not uniformly distributed.
U2L3 - Pure Substances and Mixtures
This document discusses the classification of matter. It defines pure substances as elements and compounds, which are uniform throughout and retain their properties. Mixtures are combinations of substances that are not chemically bonded and can be separated. Elements can be classified as metals, nonmetals or metalloids. Compounds are classified as organic or inorganic, acidic or basic. Mixtures are either homogeneous, with uniform composition, or heterogeneous, without uniform composition.
Made by aman
This document discusses key concepts in chemistry including:
- Chemistry is the study of matter which is anything that has mass and takes up space. All matter is made of atoms.
- Pure substances can be elements, which contain only one type of atom, or compounds, which contain two or more elements in a fixed ratio. Mixtures contain two or more substances mixed together.
- Properties describe characteristics of matter and can be physical, relating to a substance's observable properties, or chemical, relating to how it interacts with other substances.
- A chemical change forms new substances while a physical change only alters a substance's physical properties like state.
- Chemical tests can identify substances by their reactions and common tests are described
Atoms
1. Atoms are made up of subatomic particles including protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, which has a positive charge. Electrons surround the nucleus in an electron cloud and have a negative charge. (diagram)
2. The atomic number of an element is the number of protons it contains. Isotopes are atoms of the same element that differ in the number of neutrons. Ions are atoms that have gained or lost electrons, giving them an electrical charge. (table)
3. Atoms can be classified based on their composition. Elements are made
Chapter 1 typed.pptx
This document provides an introduction to general chemistry, including why chemistry is studied, its central role in understanding matter, and learning goals for the course. Chemistry involves understanding the properties and behavior of matter, which exists as elements, compounds, and mixtures. The three states of matter - solid, liquid, and gas - are classified based on molecular motion and energy. Physical and chemical properties help characterize different types of pure substances and mixtures. Changes in matter can involve physical changes of state or chemical reactions that alter chemical identity. Energy also plays a key role in these transformations.
Chemistry Chapter 1 Lesson 2 Powerpoint 2

Key concepts discussed include properties of matter, the structure of atoms and molecules, distinguishing between physical and chemical changes, and classifying different types of mixtures and pure substances.
Elements, Compounds & Mixtures Spring 2012
Elements are pure substances made of only one type of atom. Compounds contain two or more types of atoms chemically bonded together in a fixed ratio. Mixtures are physical combinations of elements and/or compounds not chemically bonded in a fixed ratio. Particles in elements are all the same type of atom. Particles in compounds have a set ratio of different atom types. Particles in mixtures retain their own identities when blended together.
Properties of matter pp
This document discusses the properties of matter including pure substances like elements and compounds, as well as mixtures. It describes the differences between heterogeneous and homogeneous mixtures and how mixtures can be classified based on particle size. The document also covers physical properties, chemical properties, and how physical and chemical changes can be distinguished.
Chapter 1 Lecture- Matter & Measurement
Chemistry is the study of properties and changes of matter. It examines matter at both the macroscopic and submicroscopic (atomic/molecular) levels. Matter exists in three main states - solids, liquids, and gases. Chemistry also studies pure substances like elements and compounds as well as mixtures. The scientific method is used to systematically study matter through experimentation and development of hypotheses and theories. Measurements in chemistry utilize metric units and scientific scales like Celsius and Kelvin.
Physical Science: Chapter 5, sec 2
A compound is composed of two or more elements that are chemically combined through a chemical reaction. During a chemical reaction, atoms of elements react and form molecules of new compounds with different properties than the original elements. Each compound has unique physical and chemical properties and elements join in specific ratios to form specific compounds.
Substances and Mixtures
This document discusses the differences between substances, mixtures, and compounds. It defines a substance as matter made of the same atoms, and notes that elements and compounds are types of substances. A mixture is two or more substances physically blended but not chemically bonded. Granite and air are given as examples of heterogeneous and homogeneous mixtures respectively. The document explains that mixtures can be separated into their original substances using physical means, while compounds require chemical changes to separate them into their component elements.

Section 2
Greece has a long history dating back to ancient Greek city-states like Athens that developed one of the first known democracies. The Byzantine Empire carried on Roman traditions for 1000 years after the Western Roman Empire fell. Today, Greece has a president and prime minister, with over 98% of Greeks practicing Greek Orthodox Christianity. Agriculture remains an important industry, with farmers growing crops like cotton, wheat and olives, and Athens is the capital and largest city despite air pollution issues.
Section 5
Rockets are able to lift off into space due to Newton's 3rd law of motion, which states that for every action force there is an equal and opposite reaction force. Satellites are objects that orbit other objects in space, such as planets, due to centripetal force keeping them in orbit around the larger object. Satellites do not fall back to Earth because the horizontal velocity of their orbit around the Earth is great enough to counteract gravitational pull, allowing them to remain in a continuous orbit.
Section 2
This document discusses friction and gravity. It defines friction as the force that two surfaces exert on each other when rubbing together, and identifies four types of friction: static, sliding, rolling, and fluid friction. Gravity is defined as a force that pulls objects toward each other. The document explains how mass and distance affect gravitational attraction between objects. It also discusses concepts related to gravity and motion like free fall, air resistance, terminal velocity, and projectile motion.
Lesson 1
The document summarizes Britain imposing taxes on its colonies through various acts of Parliament in the 1760s-1770s, which angered American colonists and led to protests. The Stamp Act of 1765 placed a tax on printed materials and was opposed by Patrick Henry and the Stamp Act Congress. The Sons of Liberty and later the Daughters of Liberty organized boycotts of British goods in response to the Townshend Acts taxing imported goods.
Section 3
The document discusses the Supreme Court of the United States. It notes that there are 9 justices, including 1 Chief Justice and 8 Associate Justices. The justices are appointed by the president. The Supreme Court has the power of judicial review to determine if laws are constitutional. It decides which cases to hear each year, accepting around 100-200 cases. Lawyers present arguments to the court and one justice writes the majority opinion.
Section 2
The document outlines the federal court system in the United States. It describes the different levels of federal courts including district courts that hold jury trials, courts of appeals that review district court cases, and the Supreme Court as the highest court. It also briefly discusses other specialty federal courts and notes that federal judges are appointed for life by the president and approved by the senate.

Section 1
The document discusses different types of laws in the United States legal system. It outlines four principal types of laws: statutory laws passed by legislatures, common laws based on precedents, administrative laws created by government agencies, and constitutional laws based on the U.S. Constitution. It also discusses some key rights in the U.S. legal system such as the right to a lawyer, right to bail, right to a jury trial, presumption of innocence, right against self-incrimination, right to cross-examine witnesses, right to accurate evidence, and right to appeal a conviction.
Lesson 4
The document describes slavery in northern and southern colonies. In the north, some slaves worked on farms while most worked in towns and cities, where they had more opportunities than southern slaves but laws still limited their rights. In the south, most slaves worked on large plantations, where some showed farmers how to raise rice. Southern slave owners could sell slaves and slaves created instruments to preserve their culture and send messages. The document also mentions slaves resisting slavery by working slowly, breaking tools, and staging rebellions like the Stono Rebellion.
Lesson 3
The document discusses various aspects of everyday life in the colonies, including education, religion, reading, and meals. It states that education was important and most schools were one room, teaching basics like reading, writing and arithmetic. It also discusses the religious landscape, with religion being important and events like the Great Awakening. Reading was a form of entertainment and important publications included the Boston News-Letter and Ben Franklin's Poor Richard's Almanac. Meals in the colonies centered around foods like corn, stew, bread and desserts.
Lesson 2
The document discusses different types of settlements in colonial America:
- Cities like Philadelphia where Benjamin Franklin established the first newspaper, public library, and volunteer fire department.
- Puritan towns in Massachusetts that were self-sufficient with crops and trade between communities. They had a common area for livestock.
- Southern plantations that grew cash crops like tobacco with slave labor under wealthy owners and managers.
- Family farms where everyone worked hard to grow their own food for survival.
Lesson 1
The document discusses minerals and rocks. It defines minerals as solid, natural materials made from nonliving substances in the ground and made up of elements. It describes properties of minerals such as luster, hardness, cleavage, and fracture. It also discusses the shapes of minerals including crystals and gems. The document then defines rocks and describes the three main types: sedimentary rocks form from compressed sediments, igneous rocks form when lava cools and hardens, and metamorphic rocks form from changes to sedimentary and igneous rocks under heat and pressure.
Section 1
A force is defined as a push or pull that can be measured in Newtons. Multiple forces can act on an object simultaneously, and the combination of all these forces is called the net force. An unbalanced net force causes an object to change its motion by starting, stopping, or changing direction, while a balanced net force where forces are equal on both sides results in no movement. The document then introduces an activity involving balloon rocket races.

Lesson 5
The document discusses weathering, erosion, and deposition. Weathering is the process by which rocks and materials break down. There are two types of weathering - physical weathering caused by temperature changes and chemical weathering caused by chemicals. Erosion is when weathered rock is moved from one place to another by forces like gravity, water, wind, etc. Deposition is when eroded materials are deposited in another location. Landforms like meanders and sandbars are created through these geological processes.
Lesson 3
Volcanoes are commonly found along tectonic plate boundaries like the Ring of Fire around the Pacific Ocean. Magma is melted rock below the Earth's surface that becomes lava when it reaches the surface. Different volcanic features like dikes, sills, and batholiths are formed by magma hardening in vertical cracks or between layers of rock. The three main types of volcanoes are shield, cinder-cone, and composite volcanoes which are distinguished by their shape and eruption patterns. Island chains like Hawaii are formed as tectonic plates move over stationary hotspots of magma or along island arcs where subduction causes magma to rise upward.
Lesson 2
The document discusses plate tectonic theory, including how geologists proposed that Earth's crust is made up of plates that move over time. It introduces Alfred Wegener's theory of continental drift, which proposed that continents move apart, and how fossil evidence later helped support this idea. It also discusses how plate tectonics can explain seafloor spreading through processes like magma formation at mid-ocean ridges. Additionally, it examines how mountain formation can occur through the compression and shearing of tectonic plates.

Chapter 5 Lesson 1
The document discusses various landforms and features of the Earth's surface and interior. It defines a landform as a physical feature on the Earth's surface and describes features of the ocean floor such as ocean basins, continental shelves, slopes, canyons, and rises. It also discusses how elevation and topographical maps are used to map Earth's landforms. Finally, it outlines Earth's major layers including the atmosphere, hydrosphere, crust, mantle, outer core, and inner core.
Lesson 4
Water ecosystems can be divided into three main categories: plankton, nekton, and benthos. 97% of the Earth is covered in salt water and 3% in fresh water. Freshwater ecosystems include rivers and streams, which are running water ecosystems, and lakes and ponds, which are standing water ecosystems. Ocean ecosystems contain several zones from the intertidal zone near the shore to the deep abyssal zone. Where salt water and fresh water meet is called an estuary, which contains a mix of both and usually salt marshes.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as âkeysâ). In fact, itâs unlikely youâll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, theyâll also be making use of the Split-Merge Block functionality.
Youâll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
