The correct statement regarding a chemical reaction is:
The total number of atoms does not change, so mass is conserved in the reaction.
This aligns with the law of conservation of mass, which states that in a closed system, the total mass of reactants must equal the total mass of products, meaning that the total number of atoms remains constant throughout the reaction.
