The true statement regarding a chemical reaction is:

The total number of atoms does not change, so mass is conserved in the reaction.

This reflects the law of conservation of mass, which states that in a closed system, matter cannot be created or destroyed during a chemical reaction. Therefore, the total number of atoms remains constant, and as a result, the mass is conserved.
