Solid calcium carbonate (limestone, CaCO3) dissolves in hydrochloric acid, producing calcium
chloride (CaCl2), carbon dioxide, and water.
CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l) ΔH° = –14.5 kJ
Suppose 25.0 g of CaCO3 is added to 475 mL of 0.750 M HCl. How much heat would be
released in the resulting reaction?
