This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite. Note: There are elements for which spellings may differ, such as aluminum/aluminium, sulfur/sulphur, and caesium/cesium.
A chemical formula describes a chemical compound using element symbols and subscripts, e.g. H 2 O for water or C 6 H 12 O 6 for glucose; SMILES is a notation for describing the structure of a molecule with a plain text string, e.g. N=N for nitrogen or CCO for ethanol
Many patients who suffer from aphasia retain the ability to produce formulaic language, including conversational speech formulas and swear words—in some cases, patients are unable to create words or sentences, but they are able to swear. Also, the ability to pronounce other words can change and evolve during the process of recovery, while ...
This is a list of CAS numbers by chemical formulas and chemical compounds, indexed by formula.The CAS number is a unique number applied to a specific chemical by the Chemical Abstracts Service (CAS).This list complements alternative listings to be found at list of inorganic compounds and glossary of chemical formulae
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
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 ...
The Hill system (or Hill notation) is a system of writing empirical chemical formulae, molecular chemical formulae and components of a condensed formula such that the number of carbon atoms in a molecule is indicated first, the number of hydrogen atoms next, and then the number of all other chemical elements subsequently, in alphabetical order ...
