Using the equations and enthalpy values provided, which mathematical expression can be used to determine the unknown enthalpy change of the decomposition of propane?
3 C + 3 O2 3 CO2 H =-1182 kJ
4 H2 + 2 O2 4 H2O H = -1144 kJ
C3H8 + 5 O2 3 CO2 + 4 H2O H = -2222 kJ
C3H8 3 C + 4 H2 H = ? kJ
(-1182) - [(-2222) + (-1144)]
(-2222) - [(-1182) + (-1144)]
(-1182) +(-1144) + (-2222)
(-2222) + (-1182) - (-1144)

I can't make out the question with no arrows to separate the products from the reactants. I'm not certain that supplying the arrows will help, either, because the board does not allow spacing after the first space.
