The correct statement about the reaction is: **The atoms of the reactants are regrouped during the reaction.**
In a chemical reaction, the atoms present in the reactants are rearranged to form the products, but the total number of each type of atom remains the same before and after the reaction. Therefore, the first statement is true.
The other statements are incorrect:
- Some atoms gaining mass after the reaction is false; mass is conserved in a chemical reaction.
- Atoms of Na are not destroyed during the reaction; they are simply rearranged.
- There are not more H atoms after the reaction; the number of hydrogen atoms is conserved.
Thus, the first response is the correct one.
