The correct response is 4. After the reaction, there are still four atoms of hydrogen present.
The correct statement about the reaction is:
The atoms of the reactants are regrouped during the reaction.
To determine the correct statement about the given chemical reaction (NaHCO3 + HC2H3O2 -> NaC2H3O2 + H2O + CO2), we need to analyze the reaction and understand what happens to the atoms involved.
In this reaction, NaHCO3 (sodium bicarbonate, also known as baking soda) and HC2H3O2 (acetic acid) are the reactants. NaC2H3O2 (sodium acetate), H2O (water), and CO2 (carbon dioxide) are the products.
Based on the balanced chemical equation, we can see that the components of the reactants are rearranged to form the products. Therefore, the correct statement is:
The atoms of the reactants are regrouped during the reaction.
This means that the atoms of the reactants do not get destroyed; instead, they are rearranged to form different compounds in the products of the reaction.
