The true statement regarding a chemical reaction is: The total number of atoms does not change, so mass is conserved in the reaction.

This is based on the law of conservation of mass, which states that in a closed system, the total mass of the reactants must equal the total mass of the products, as no atoms are created or destroyed in a chemical reaction.
