Use the chemical reaction to answer the question.

NaHCO3+HC2H3O2→NaC2H3O2+H2O+CO2
A student mixes baking soda (NaHCO3) and acetic acid (HC2H3O2) to produce a chemical reaction shown. Which statement about the reaction is correct?

(10 point)

The atoms of the reactants are regrouped during the reaction.

Some atoms gain mass after the reaction.

There are more H atoms after the reaction.

Atoms of Na are destroyed during the reaction.

During a chemical reaction, no atoms are destroyed or created. The change occurred in the given reaction is the regrouping of atoms of the reactants.

A change by which a bond between two atoms is created or breaks called chemical changes. All chemical and biological reactions are example of chemical changes.

According to law of conservation of mass proposed by Antoine Lavoisier  mass is neither created nor destroyed. Thus the total mass in a reaction is conserved.

The mass in reactant side must be equal to the mass in the product side in a balanced reaction. Thus no atoms crated or destroyed.

Therefore, option A is correct, that is atoms are regrouped between reactants during a reaction to get new products with same mass as that in product side.
