Answer 1

The correct statement about the reaction is: The atoms of the reactants are regrouped during the reaction.

In a chemical reaction, atoms are rearranged to form new substances, but no atoms are created or destroyed, and the total mass remains constant. Therefore, the other statements regarding the number of H atoms increasing, the destruction of Na atoms, and the gain in mass are incorrect.
