Find ?Hrxn for the following reaction: 2CdS(s) + 3O2(g) ? 2CdO(s) + 2SO2(g) Use the following reactions with known ?H values: 2H2S(g) + O2(g) ? 2S(s, rhombic) + 2H2O(g) ?H = -442.4 kJ S(s, rhombic) + O2(g) ? SO2(g) ?H = -296.8 kJ CdO(s) + H2S(g) ? CdS(s) + H2O(g) ?H = -124.7 kJ Express the energy to one decimal place and include the appropriate units. ?Hrxn = 786.6 kJ

          Find ?Hrxn for the following reaction:
2CdS(s) + 3O2(g) ? 2CdO(s) + 2SO2(g)

Use the following reactions with known ?H values:
2H2S(g) + O2(g) ? 2S(s, rhombic) + 2H2O(g) ?H = -442.4 kJ
S(s, rhombic) + O2(g) ? SO2(g) ?H = -296.8 kJ
CdO(s) + H2S(g) ? CdS(s) + H2O(g) ?H = -124.7 kJ

Express the energy to one decimal place and include the appropriate units.
?Hrxn = 786.6 kJ
