The law of chemical reactions refers to the fundamental principles that govern chemical reactions and how substances transform into new substances.


Chemical combination occurs in definite proportion by weight or by volume. Based on various experiments performed by different scientists, the laws of chemical combinations were formulated.
There are five laws of chemical combinations. The first four deal with combination of substances by
weight and the fifth with combination of gases by volume.
