    Use the data sheet to calculate Delta H, Delta S and Delta G at 25 degrees Celsius for each of the following reactions. In each case show that Delta G- Delta H-T Delta S.

    1. Ni(s) + Cl2(g) --> NiCl2(s)
    2. CaCO3(s, calcite) --> CaO(s) + CO2(g)
    3. 2CH2OH(l) + 3O2(g) --> 2CO2(g) + 4H2O(l)

    Please see the attached document for the data sheet.

    1. Ni(s) + Cl2 (g) ---> NiCl2 (s)

    dH = heat of formation of products - heat of formation of reactants
    dH = -305.3 - [ 0 + 0] = -305.3 kJ/mol
    dS = 97.65 - [29.9 + 222.96] = -155.21 J/mol = -0.1552 kJ/mol
    dG = -259.0 -[0 ...
