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) Responses Atoms of Na are destroyed during the reaction. Atoms of Na are destroyed during the reaction. Some atoms gain mass after the reaction. Some atoms gain mass after the reaction. The atoms of the reactants are regrouped during the reaction. The atoms of the reactants are regrouped during the reaction. There are more H atoms after 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 are rearranged to form new products. Thus, while the chemical composition changes, the total number of each type of atom remains the same before and after the reaction.
