Chemical laws
Main article: Chemical law
Chemical reactions are governed by certain laws, which have become fundamental concepts in chemistry. Some of them are:§ Avogadro's law
§ Beer-Lambert law
§ Boyle's law (1662, relating pressure and volume)
§ Charles's law (1787, relating volume and temperature)
§ Fick's law of diffusion
§ Gay-Lussac's law (1809, relating pressure and temperature)
§ Henry's law
§ Hess's Law
§ Law of conservation of energy leads to the important concepts of equilibrium, thermodynamics, and kinetics.
§ Law of conservation of mass, according to the modern physics it is actually energy that is conserved, and that energy and mass are related; a concept which becomes important in nuclear chemistry.
§ Law of definite composition, although in many systems (notably biomacromolecules and minerals) the ratios tend to require large numbers, and are frequently represented as a fraction.
§ Law of multiple proportions
Raoult's Law
