Critical temperature
Chemistry; General chemistry
The temperature at the critical point . A gas above the critical temperature will never condense into a liquid, no matter how much pressure is applied. Most substances have a critical temperature ...
Law of multiple proportions
Chemistry; General chemistry
When one element can combine with another to form more than one compound, the mass ratios of the elements in the compounds are simple whole-number ratios of each other. For example, in CO and in CO2, ...
Solubility product
Chemistry; General chemistry
The equilibrium constant for a reaction in which a solid ionic compound dissolves to give its constituent ions in solution.
Azo
Chemistry; General chemistry
The azo group has the general structure Ar-N=N-Ar', where Ar and Ar' indicate substituted aromatic rings . Compounds containing the azo compounds are often intensely coloured and are economically ...
Glycerol
Chemistry; General chemistry
Glycerol is a small molecule with three alcohol groups. It is a basic building block of fats and oils.
Phase change
Chemistry; General chemistry
A change in the state of a sample of matter; for example, solid to liquid or liquid to gas. Phase changes are considered physical rather than chemical changes.
Wavenumber
Chemistry; General chemistry
The number of wave crests per unit distance. Wavenumber is the reciprocal of wavelength . Wavenumbers are used extensively in infrared spectroscopy , and usually have units of cm-1.
