Answer:
Option (b) is the correct response. When the mass of atoms of different elements in the reactants side equals the mass of atoms in the products side, the equations are balanced.
The chemical equations are balanced to satisfy one of the following laws in chemical reactions. This law is known as (a) Law of conservation of momentum (b) Law of conservation of mass (c) Law of conservation of motion (d) Law of conservation of magnetism
