Responses

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

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.

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.

In a chemical reaction, atoms are neither created nor destroyed (the law of conservation of mass), but they are rearranged to form new products. Therefore, the other options regarding mass gain, an increase in H atoms, or the destruction of Na atoms are incorrect.
