The NCAC was founded as the Far Western Conference (FWC) in 1925 by its charter member schools: Fresno State, Saint Mary's, UC Davis, Nevada, San Jose State and College of the Pacific. [ 2 ] Nevada's departure from the conference in 1940 left the conference with only four members: Chico State , Fresno State, College of the Pacific and UC Davis ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Femtochemistry is the area of physical chemistry that studies chemical reactions on extremely short timescales (approximately 10 −15 seconds or one femtosecond, hence the name) in order to study the very act of atoms within molecules (reactants) rearranging themselves to form new molecules (products).
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
The following outline acts as an overview of and topical guide to chemistry: . Chemistry is the science of atomic matter (matter that is composed of chemical elements), especially its chemical reactions, but also including its properties, structure, composition, behavior, and changes as they relate to the chemical reactions.
In traditional nomenclature, the first carbon atom after the carbon that attaches to the functional group is called the alpha carbon; the second, beta carbon, the third, gamma carbon, etc. If there is another functional group at a carbon, it may be named with the Greek letter, e.g., the gamma-amine in gamma-aminobutyric acid is on the third ...
The A-value for a methyl group is 1.74 as derived from the chemical equilibrium above. This means it costs 1.74 kcal/mol (7.3 kJ/mol) of energy to have a methyl group in the axial position compared to the equatorial position.
The main group elements are the elements of groups 1, 2, and 13–18 (i.e. the s-block and p-block). [5] The transition elements are the elements of groups 3–12 (i.e. the d-block) – this in particular includes group 12 (although some sources do not include it). [5] The inner transition elements are f-block elements. [2]
