Homework Statement
Given the following reactions
Fe2O3 + 3CO ---> 2Fe + 3CO2 DeltaH = -28.0kJ
3Fe + 4CO2 ---> 4CO + Fe3O4 DeltaH = 12.5kJ
the enthalpy of the reactions of Fe2O3 with CO
3Fe2O3 + CO ---> CO2 +2Fe3O4
what is DeltaH for this equation? ________ kJ
Homework Equations
DeltaH = H(products) - H(reactants)
The Attempt at a Solution
I've tried to switch the equations around to isolate certain solutions but I've had no luck at all, I would really appreciate some help on this problem.
