Answer 1

The correct statement regarding the Law of Conservation of Mass in a chemical reaction is:

In a chemical reaction, mass is neither created nor destroyed.

This law states that the total mass of reactants in a chemical reaction is equal to the total mass of the products, meaning that atoms are simply rearranged and no mass is lost or gained.
