Chemical laws

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 punduathe 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
