Question

NaHCO3+HC₂H₃O₂→ NaC₂H₂O₂ + H₂O + CO₂

A student mixes baking soda (NaHCO₂) and acetic acid (HC₂H₃O₂) to produce a chemical reaction shown. Which statement about the reaction is correct?

(1 point)

Atoms of Na are destroyed during the reaction.

The atoms of the reactants are regrouped during the reaction

There are more H atoms after 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.

This statement reflects that during a chemical reaction, the atoms present in the reactants are rearranged to form the products, without any atoms being destroyed or gained. The law of conservation of mass states that atoms cannot be created or destroyed in a chemical reaction, so Na atoms cannot be destroyed, and the total number of H atoms remains the same before and after the reaction. Additionally, atoms do not gain mass during the reaction; the mass is conserved.
