Elements, Compounds and Mixtures
This document discusses the classification of matter. It explains that scientists classify matter based on its composition and whether it is uniform throughout. There are three main types of matter: mixtures, elements, and compounds. Mixtures are two or more substances that are not chemically combined and can be separated physically. Elements are the simplest pure substances that cannot be broken down further. Compounds are pure substances made of two or more elements that can be broken down chemically into simpler substances.
elements compond and molecules
There are three main types of matter: elements, compounds, and mixtures. Elements are pure substances made of only one type of atom, while compounds are made of two or more elements chemically bonded together. Compounds are represented by chemical formulas that use symbols to show what elements are present and in what ratios. Mixtures are combinations of elements or compounds that are not chemically bonded and whose components retain their individual properties. Common examples are water (H2O), salt (NaCl), carbon dioxide (CO2), and air.

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.
Lesson 4 mixture and substance
This document discusses the differences between pure substances and mixtures. It defines pure substances as elements or compounds that have only one type of particle throughout. Mixtures contain two or more substances that are not chemically combined. Mixtures can be either heterogeneous, where the different components can be easily observed, or homogeneous, where the components are evenly distributed and not visible to the eye. Examples of heterogeneous mixtures include mixtures of different solids, liquids, or gases, while homogeneous mixtures have their components distributed evenly throughout.
Elements and Compounds PowerPoint.ppt
Elements are the basic building blocks that make up all matter in the universe, of which there are about 100. Compounds are formed when two or more elements chemically bond together in a fixed ratio represented by a chemical formula. The periodic table organizes the elements and provides information about their properties. Molecules are the smallest units of compounds and elements, such as water (H2O) which is a molecule made of hydrogen and oxygen atoms. Compounds differ from elements in that they have unique properties determined by the bonded elements.

Matter matters
1) Matter is anything that takes up space and can be classified into states such as solid, liquid, or gas. Matter is made up of tiny particles called atoms.
2) Atoms are the smallest unit of matter that make up elements. Elements contain only one type of atom and cannot be broken down further. Atoms themselves are made up of even smaller subatomic particles like protons, neutrons, and electrons.
3) Atoms can bond together to form molecules or crystalline structures. Molecules contain two or more different atoms chemically bonded together. Compounds have different properties than their constituent elements. Mixtures can contain elements, compounds, or both and their components can often be separated physically.

02_Is Matter Around Us Pure.pdf
This document discusses pure and impure substances. It defines a pure substance as consisting of only one component that cannot be separated, while an impure substance contains two or more components that can be separated. Pure substances are either elements or compounds. Elements are made of one type of atom, while compounds contain two or more elements chemically bonded together. Mixtures are impure substances containing elements or compounds mixed but not chemically bonded. Mixtures can be either homogeneous, containing components mixed at the molecular scale, or heterogeneous with visible separation of components. Common homogeneous mixtures include solutions and airs, while suspensions and colloids have larger but still microscopically mixed components and are also considered heterogeneous mixtures.
Elements,compounds and mixtures
Elements are pure substances that cannot be broken down further by chemical reactions or processes. They consist of only one type of atom and exist as either individual atoms or molecules made of atoms of the same element. Compounds are pure substances made of two or more elements chemically bonded together in fixed ratios. Compounds have distinct properties and can be broken down into their constituent elements. Mixtures are physical combinations of elements or compounds not chemically bonded. They do not have a fixed composition and their properties depend on the substances that make them up. Mixtures can be separated into their components using physical processes like filtration or evaporation.
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.
CLASSIFICATION OF matter.pptx
This document discusses the classification of matter. It defines a pure substance as matter that has a definite and uniform chemical composition and properties that cannot be separated into simpler substances by physical means. Pure substances can be elements, which are made of a single type of atom, or compounds, made of two or more different types of atoms bonded together. Elements are the basic building blocks of matter and cannot be broken down further. The document also defines mixtures as combinations of two or more pure substances that retain their individual properties and can be separated physically. Mixtures can be either homogeneous, where the components are uniformly mixed, or heterogeneous, where the components separate visually.
Compounds And Mixtures
Compounds are substances composed of two or more elements that are chemically combined to form a new substance with new properties. A compound contains atoms of elements in a fixed ratio, with each particle containing the same elements in the same proportions. Mixtures are combinations of substances that are not chemically combined and can be separated using physical properties. Common compounds that make up living things include water, proteins, and DNA.
COMPOUNDS
A compound is a pure substance composed of two or more elements chemically bonded together, such as sodium chloride or water. Compounds can only be broken down or formed through a chemical reaction that breaks and rearranges bonds between atoms. Some common compounds found in homes include sodium chloride, water, glucose, and other substances containing ionically or covalently bonded elements.
grade7-elements and compounds.pptx
The document discusses the key differences between elements and compounds. Elements are made of single atoms of the same type and cannot be broken down further, while compounds are made of two or more elements chemically bonded together. Compounds can be broken down into their component elements through chemical processes, but elements cannot. The document provides examples of common elements like iron and compounds like water and salt.
Unit 2 Power Point
1. Matter is composed of protons, neutrons, and electrons. Protons define the element, while neutrons define the isotope.
2. An element is the most basic form of matter and is defined by its number of protons. Elements usually have an equal number of protons and electrons.
3. Isotopes are variations of the same element that have a different number of neutrons, which affects mass but not chemical properties.

The document contrasts compounds and mixtures and discusses different types of mixtures like solutions, colloids, and suspensions.
2-1 Classifying Matter
The document discusses classifying different types of matter. It defines pure substances as elements and compounds, which have fixed compositions. Elements contain only one type of atom, while compounds are made of two or more simpler substances combined in fixed ratios. Mixtures are not pure substances and can be either heterogeneous, containing visible parts of differing substances, or homogeneous, containing substances evenly mixed together on a microscopic scale. Common homogeneous mixtures include solutions, where a solute dissolves evenly in a solvent.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

ELEMENTS AND COMPOUNDS.pptx
- 1. How substances differ from mixtures? All substances are homogeneous Some mixtures are also homogeneous Can you identify which of the following is a substance or a mixture? Pure Water Substance Water + Salt Mixture (Homogeneous)
- 5. Take a look at this! Copper and Water are both pure substances. Copper =1 copper atom Water =2 hydrogen atoms +1 oxygen atom
- 6. Elements Are said to be the building blocks of matter. These cannot be broken down into simpler substances simply because it is the simplest form of matter. There are about 118 elements. Most of these elements are naturally occurring and only a small percentage of elements are man-
- 9. Compounds A compound is a combination of elements. But remember that a compound is a chemical combination of two or more elements. A chemical combination results to a formation of a new substance.
