Verified step by step guidance1
Identify the reactants and products in the chemical equation. Reactants are substances present before the reaction occurs, and products are substances formed as a result of the reaction.
Look at the given equation: \(\text{NaOH} + \text{HCl} \rightarrow \text{NaCl} + \text{H}_2\text{O}\). The substances on the left side of the arrow are the reactants, and those on the right side are the products.
Label the species on the left side: \(\text{NaOH}\) and \(\text{HCl}\) are the reactants because they are the starting materials that react together.
Label the species on the right side: \(\text{NaCl}\) and \(\text{H}_2\text{O}\) are the products because they are formed after the reaction takes place.
Compare your labeling with the options provided to select the correct statement that matches this identification.
