What are the building blocks of matter
This document defines key chemistry terms including atoms, molecules, elements, compounds, mixtures, and solutions. Atoms are the smallest unit of matter that cannot be divided further. Molecules are formed when two or more atoms combine chemically. Matter is made up of elements, compounds, mixtures, and solutions. Elements are made of the same type of atom, compounds contain two or more types of atoms bonded together with a specific chemical formula. Mixtures contain elements or compounds that are not chemically bonded. Solutions occur when a solute dissolves evenly throughout a solvent.
Carbon-12 scale
1) Relative atomic mass (RAM) is a measurement of how many times heavier an atom is than 1/12 the mass of one carbon-12 atom. Relative molecular mass (RMM) similarly compares the mass of a molecule to 1/12 the mass of one carbon-12 atom.
2) Scientists first used hydrogen as the standard for RAM/RMM but switched to oxygen and finally settled on carbon-12 due to its stability and prevalence.
3) The document provides examples of calculating RAM and RMM values for various elements and compounds using the relative scales and given atomic mass values.
Relative molecular mass and percentage composition
The relative molecular mass (Mr) of a molecule is calculated by adding the relative atomic masses of all the atoms in the molecule. It is a ratio comparing the average mass of a molecule to 1/12 the mass of one atom of carbon-12 or one hydrogen atom. Some examples are given of calculating the Mr of carbon dioxide (CO2), sugar (C12H22O11), and sulfuric acid (H2SO4). The percentage composition of elements in compounds can be calculated from the formula and relative atomic masses. The mass of an element in a sample can then be determined from the percentage composition and total mass of the compound. Empirical formulas can be determined from the masses of elements that combine or from percentage

Diffusion of gases
Diffusion is the movement and mixing of gas particles. It occurs more quickly for gases than liquids and at higher temperatures. In one experiment, ammonia and hydrochloric acid gases diffuse towards each other in a sealed tube and react to form ammonium chloride particles. Ammonia particles diffuse faster because they have a lower molar mass than hydrochloric acid particles. Graham's law states that the rate of effusion, or movement through a small hole, is inversely proportional to the square root of a gas's molar mass.

Atoms are the basic building blocks that make up all matter. Atoms contain a nucleus with positively charged protons and neutral neutrons surrounded by negatively charged electrons. Elements are made of only one type of atom, while compounds contain two or more elements bonded together. There are two main types of bonds between atoms - covalent bonds formed by shared electron pairs and ionic bonds formed between oppositely charged ions. Water is a polar molecule that is essential for life and has unique properties like being a universal solvent and having a high heat capacity. The four main types of biomolecules are carbohydrates, lipids, proteins, and nucleic acids, each with distinct structures that allow them to perform important functions in living things.

2.2 water
Water is essential for life due to its unique properties arising from its molecular structure and polarity. Water molecules are polar due to an uneven distribution of charge, with oxygen exerting a pull on shared electrons making it slightly negative and hydrogen slightly positive. This allows water to form hydrogen bonds between molecules, giving water high melting and boiling points, heat capacity, and the ability to dissolve many other polar substances. Water's polarity allows it to act as a solvent and universal medium for critical biological and chemical processes on Earth.

Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.

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).

Relative masses of atoms and molecules
- 1. Done By: Eric Seow
- 2. • Masses of particles are often numbers which are very small and inconvenient • Relative mass is used in practice by chemists
- 3. • Lightest atom is the hydrogen atom • One nitrogen atom is 14 times heavier than a hydrogen atom; nitrogen has a relative atomic mass of 14 • One iron atom is 56 times heavier than a hydrogen atom; iron has a relative atomic mass of 56
- 4. • Molecules consist of atoms joined together • Relative molecular mass is the average mass fo one molecule of a substance when compared with 1/12 of the mass of one atom of carbon-12 • Symbol is M1
- 5. • Is found by adding up the relative atomic masses of all the atoms in the forumla
- 6. • Can be calculated from the formula of a compound • Can be calculated from the relative atomic mass of the elements of the compound
- 7. • Knowing the mass of an element in a compound, the mass of the element in a sample of the compound can be calculated
- 8. • Some compounds contain water • Said to be hydrated • Have H20 in their formula • Formula is CuSO4.5H2O • The mass of water in a compound can then be calculated •
