Question
Calculate the standard enthalpy of formation of CuO2, given that:
2Cu2O + O2 ==> 4 CuO (-288 kJ)
Cu2O ==> Cu + CuO (11 kJ)
PLEASE HELP!!!!
2Cu2O + O2 ==> 4 CuO (-288 kJ)

You need to examine your post. Nowhere in your post does CuO2 appear except in the question. Neither equation contains CuO2.

Standard enthalpy of formation is creating a compound from it's elements- you don't need the equation DrBob222.
The equation would read: Cu + O2 yields CuO2.
Then use Hess's law to figure it out.
