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

Correct Answer: (b) law of conservation of mass.

Explanation: The chemical equations are balanced to satisfy the law of conservation of mass, which states that "matter can neither be created nor be destroyed". If the numbers of atoms of various elements are different in reactants' and products' side, it means they are either destroyed or created, which violate the law of conservation of mass.
