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

Explanation: In ordinary chemical reactions atoms are only rearranged (not created or destroyed), so the total mass before and after is the same (law of conservation of mass). (Exception: nuclear reactions involve changes in nuclei and can change mass/identity of atoms.)
