(Law) A required aspect or component of a cause of action. A deed is regarded a violation of law only if each element can be proved.
A substance consisting of atoms or ions of two or more different elements in definite proportions joined by chemical bonds into a molecule. The elements cannot be separated by physical means. Water, for example, is a compound having two hydrogen atoms and one oxygen atom per molecule.
Something that serves as a remedy or corrective:
The radical CNH, having a double bond between the carbon and nitrogen atoms.
Any of a large number of chemicals made from petroleum or natural gas. Important petrochemicals include benzene, ammonia, acetylene, and polystyrene. Petrochemicals are used to produce a wide variety of materials, such as plastics, explosives, fertilizers, and synthetic fibers.
A substance that starts or speeds up a chemical reaction while undergoing no permanent change itself. The enzymes in saliva, for example, are catalysts in digestion.
An organic compound formed when an acid and an alcohol combine and release water. Esters formed from carboxylic acids are the most common, and have the general formula RCOOR&STRESS;, where R and R&STRESS; are organic radicals. Esters formed from simple hydrocarbon groups are colorless, volatile liquids with pleasant aromas and create the fragrances and flavors of many flowers and fruits. They are also used as food flavorings. Larger esters, formed from long-chain carboxylic acids, commonly occur as animal and vegetable fats, oils, and waxes. Esters have a wide range of uses in industry.

Any of various organic compounds, such as pyridine or pyrimidine, that have a ring structure like that of benzene but with one or more carbon atoms replaced by a nitrogen atom. Azines are heterocyclic compounds.
A colorless or white crystalline salt in which a sodium atom (the cation) is bonded to a chlorine atom (the anion). This salt is found naturally in all animal fluids, in seawater, and in underground deposits (when it is often called halite ). It is used widely as a food seasoning and preservative. Also called common salt, sodium chloride, table salt. Chemical formula: NaCl.
Acid is defined as something that has a sour taste, or something that has a pH of less than 7 in chemistry.
