Question

Briefly explain laws of chemical combinations.

Answer 1

Laws of chemical combinations are laws that have been established based on various experiments on matter and chemical reactions. Examples of these laws include:

$\text{Law of Conservation of Mass}$: This law states that matter can neither be created nor be destroyed. In other words, the total mass, that is, the sum of the masses of all reactants and products remains constant.

$\text{Law of Constant Proportions}$: Joseph Proust, stated that in a chemical substance, the elements are always present in definite proportions by mass.
