Question:

The Romans used calcium oxide, CaO, to produce a strong mortar to build stone structures. Calcium oxide was mixed with water to give Ca(OH)₂, which reacted slowly with CO₂ in the air to give CaCO₃.

(a) Calculate the standard enthalpy change for this reaction.

(b) How much energy is evolved or absorbed as heat if 1.00 kg of Ca(OH)₂ reacts with a stoichiometric amount of CO₂?
