Which one of the following statements is NOT a correct statement of the Law of Conservation of Mass?

a) The mass of a system is conserved in a chemical reaction.

b) The mass cannot be created or destroyed by chemical reactions.

c) The mass of a system is dependent upon chemical reactions that may occur.

d) Atoms are conserved in chemical reactions.

c) The mass of a system is dependent upon chemical reactions that may occur.

Explanation:

Law of Conservation of Mass -

Also called the principle of mass conservation, this law was first independently given by the scientist Mikhail Lomonosov and later was rediscovered in 18th century by the father of chemistry Antoine Lavoisier.

According to this law, for a closed system, the mass of the system remains constant, before and after a reaction.

Therefore, the mass is conserved for a chemical reaction.

The statement a, b, d are completely correct,

But the incorrect statement is the c, because the mass of the system is independent of the chemical reaction.
