36. Calculate the heat of formation of calcium hydroxide, based on the following thermochemical equations:
(1) Ca(c) 1/2O2(g) = CaO(c); ΔН = -635.60 kJ;
(2) H2(g) 1/2O2(g) = H2O(l); ΔН = -285.84 kJ;
(3) CaO(c) H2O(l) = Ca(OH)2(c); ΔН = -65.06 kJ.
How much heat will be released (absorbed) in the reaction proceeding according to equation (3),
