    Using H-H 432.0, Cl-Cl = 239.7, H-Cl = 428.0, determine the rH for the reaction:
    H?H (g) + Cl?Cl(g) 2H?Cl (g)

    2. If the rH of combustion of CH4 is -802kJ/mol. How many grams of water, which has a specific heat of 4.184 J/g-oC, can be heated from 20oC to 90oC by combustion of 2.00 mol of CH4?
