Answer 1

The correct statement is: The atomic mass of the reactants equals the atomic mass of the product, and the product has the same number of atoms as the reactants.

This demonstrates the conservation of mass because, during a chemical reaction, the total mass of the reactants (hydrogen and oxygen) is equal to the total mass of the product (water), indicating that matter is neither created nor destroyed in the reaction.
