The following two laws of chemical combination were established after much experimentations by Lavoisier and Joseph L. Proust.
`color{green}("πππ° π¨π ππ¨π§π¬ππ«π―πππ’π¨π§ π¨π π¦ππ¬π¬")`
Law of conservation of mass states that mass can neither be created nor destroyed in a chemical reaction.
`color{green}("πππ° π¨π ππ¨π§π¬πππ§π π©π«π¨π©π¨π«ππ’π¨π§π¬")`
`color{green}(β’)` This law was stated by Proust as βIn a chemical substance the elements are always present in definite proportions by massβ.
`color{green}(β’)` For eg: In a compound such as water, the ratio of the mass of hydrogen to the mass of oxygen is always 1:8, whatever be the source of water. Thus, if 9 g of water is decomposed, 1 g of hydrogen and 8 g of oxygen are always obtained. Similarly in ammonia, nitrogen and hydrogen are always present in the ratio 14:3 by mass, whatever be the method of preparation.
