The reaction of quicklime, CaO, with water produces slaked lime, Ca(OH)2, which is widely used in theconstruction industry to make mortar and plaster. The reaction of quicklime and water is highly exothermic:CaO(s) + H2O(l) ⟶ Ca(OH)2(s) ΔH = −350 kJ mol−1(a) What is the enthalpy of reaction per gram of quicklime that reacts?(b) How much heat, in kilojoules, is associated with the production of 1 ton of slaked lime?
