When 1.045 g оf BаO is аdded tо 100.0 ml оf wаter at 22.0 oC in a coffee-cup calorimeter, the temperature of the water increases to 25.7 oC. Assume that the specific heat and density of the solution is 4.184 J/g∙oC and 1.00g/ml, respectively. The heat capacity of the calorimeter is 25.0 J/oC. Calculate ΔH for the reaction. BaO(s) + H2O(l) → Ba(OH)2(aq); ΔH = __________
