The stoichiometric relationship between the reactants and products of an aqueous reaction can be used to determine different kinds of information about a reaction, such as the volume of a given molarity reactant required to produce a certain amount of product. Hydrochloric acid (HCl) reacts with sodium carbonate (Na2CO3), forming sodium chloride (NaCl), water (H2O), and carbon dioxide (CO2). This equation is balanced as written: 2HCl(aq)+Na2CO3(aq)→2NaCl(aq)+H2O(l)+CO2(g) a. What volume of 2.50 M HCl in liters is needed to react completely...
