Question

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 (Na CO2). forming sodium chloride (NaCl), water (HO), and carbon dioxide (C0.). This equation is balanced as written: 2HCl(aq) + Na, CO, (aq)-2NaCl(aq) + H,0(1) + CO2(g) Part A What volume of 1.25 M HCl in liters is needed to react completely (with nothing left over) with 0.250 L of 0.200 M NA, CO,? Express your answer to three significant figures and include the appropriate units. View Available Hint(s) HAR O ?
