Calculate the amount of heat in kilojoules released when 50 grams of steam at 125 degrees C are converted to 50 grams of ice at -125 degrees C. Specific heat capacities are: ice, 2.03 J/g C; Liquid, 4.2 J/g C; Steam: 2.0 J/g C. DeltaH vap is 40.7 kJ/mol and DeltaH fusion is 6.02 kJ/mol.
If 0.215 mole of calcium chloride is dissolved in 491.9 ml of water, how much will it change the temperature of water (FWt=18.02)? The delta H=-81.3 kJ/mole for CaCl2
