This Law was given by Mikhail Lomonosov.
This law states that “the total mass can neither be created nor destroyed but can be converted from one form to another during a chemical reaction”.
Explanation:
Since all the matter is composed of atoms, therefore, atoms can neither be created nor destroyed during a chemical reaction.
Total number of atoms of reactants is always equal to the total number of atoms of products.
Consider the following equation:
C+O2 — →CO2
Total number of atoms of reactants = 6.02 X 1023 atoms of C+ (2 x 6.02 X 1023) atoms of O
= 3 x 6.02 X 1023 atoms
Total number of atoms of product = 3 X 6.02 X 1023 atoms
Total number of atoms of reactants = Total number of atoms of product
