Question

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?
(1 point)
there are more h atoms after the reaction.
the atoms of the reactants are regrouped during the reaction.
some atoms gain mass after the reaction.
atoms of na are destroyed during the reaction.

Explanation:

• According to the law of conservation of mass, atoms are neither created nor destroyed in a chemical reaction. So options "There are more H atoms after the reaction", "Some atoms gain mass after the reaction", and "Atoms of Na are destroyed during the reaction" are incorrect.
• In a chemical reaction, the atoms of the reactants are regrouped to form products. This is what happens in the given reaction \(NaHCO_3 + HC_2H_3O_2

ightarrow NaC_2H_3O_2 + H_2O + CO_2\).

Answer:

The atoms of the reactants are regrouped during the reaction.
