Verified step by step guidance1
Identify the reactants and products in the given chemical equation: \(\mathrm{HCl(aq) + NaHCO_3(aq) \rightarrow CO_2(g) + H_2O(l) + NaCl(aq)}\).
Recall that reactants are the substances present before the reaction occurs, located on the left side of the arrow.
Note that products are the substances formed as a result of the reaction, located on the right side of the arrow.
From the equation, the substances on the left side (reactants) are \(\mathrm{HCl(aq)}\) and \(\mathrm{NaHCO_3(aq)}\).
Therefore, the correct list of reactants is \(\mathrm{HCl(aq)}\) and \(\mathrm{NaHCO_3(aq)}\).
