Responses

There are more H atoms after the reaction.
There are more H atoms after the reaction.

Atoms of Na are destroyed during the reaction.
Atoms of Na are destroyed during the reaction.

Some atoms gain mass after the reaction.
Some atoms gain mass after the reaction.

The atoms of the reactants are regrouped during the reaction.

Answer 1

The correct statement about the reaction is:

**The atoms of the reactants are regrouped during the reaction.**

This is because, in a chemical reaction, atoms are neither created nor destroyed; they are simply rearranged to form new substances. The other statements are incorrect because the number of hydrogen atoms remains the same, sodium atoms are not destroyed (they simply become part of a different molecule), and atoms do not gain mass in a chemical reaction.
