1 answer
The correct statement about the reaction is:
The atoms of the reactants are regrouped during the reaction.
In a chemical reaction, the atoms in the reactants are rearranged to form new products, but no atoms are created or destroyed, and the total mass remains the same. The number of hydrogen (H) atoms, as well as the atoms of sodium (Na), remains balanced before and after the reaction. Therefore, the first statement is the only accurate choice regarding the process occurring in this reaction.
