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 There are more H atoms after the reaction. There are more H atoms after the reaction. Atoms of Na are destroyed during the reaction. Atoms of Na are destroyed during the reaction. The atoms of the reactants are regrouped during the reaction. The atoms of the reactants are regrouped during the reaction. Some atoms gain mass after the reaction.
The correct statement about the reaction is: The atoms of the reactants are regrouped during the reaction.
The correct statement about the reaction is: The atoms of the reactants are regrouped during the reaction.
To determine which statement about the reaction is correct, we need to analyze the balanced chemical equation:
NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2
From the equation, we can see that the reactants are sodium bicarbonate (NaHCO3) and acetic acid (HC2H3O2), while the products are sodium acetate (NaC2H3O2), water (H2O), and carbon dioxide (CO2).
Now, let's evaluate each statement one by one:
1. There are more H atoms after the reaction.
To check this, we need to compare the number of H atoms in the reactants with the number of H atoms in the products. In the reactants, there is one H atom in acetic acid (HC2H3O2). In the products, there are two H atoms in water (H2O). Therefore, there are more H atoms after the reaction. This statement is correct.
2. Atoms of Na are destroyed during the reaction.
To determine this, we compare the number of Na atoms in the reactants with the number of Na atoms in the products. In the reactants, there is one Na atom in sodium bicarbonate (NaHCO3). In the products, there is one Na atom in sodium acetate (NaC2H3O2). Therefore, Na atoms are not destroyed during the reaction. This statement is incorrect.
3. The atoms of the reactants are regrouped during the reaction.
This statement is correct. In a chemical reaction, the atoms of the reactants rearrange to form new compounds or molecules in the products. This balanced equation demonstrates such rearrangement.
4. Some atoms gain mass after the reaction.
To evaluate this statement, we need to analyze the mass of the atoms involved. However, based on the given information, we cannot determine any change in mass. Therefore, this statement cannot be determined from the given data.
In conclusion, the correct statement about the reaction is: "There are more H atoms after the reaction."
