Responses

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

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

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 not created or destroyed; they are rearranged to form new products. The mass of the system remains constant, adhering to the law of conservation of mass. Therefore, the other statements are incorrect. There are not more H atoms after the reaction; the Na atoms are not destroyed; and atoms do not gain mass; they are simply rearranged.
