Solution

The correct option is B False
Law of Conservation of mass states that mass can neither be created nor be destroyed in a chemical reaction.
This law was given by Antoine Lavoisier.
According to this law, in a chemical reaction, the mass of the reactants and the products remains the same.
Thus, the given statement is false.
