question 2

Asked by ron | Jan 1, 2003
This question find difficult to do: Suppose you were given the enthalpy changes for the following reactions: 2Fe + 1.5O2 = Fe2O3 Ca + 1.5O2 = CaO How will you calculate the enthalpy changes for each of the following reactions: a) 3Ca + Fe2O3 = 3CaO + 2Fe b) Ca +CuO = CaO + Cu c) 2Fe + 3CuO = Fe2O3 +3Cu This shows I am finding it difficult using hess's law. Can you please help me on the questions. Thankyou Jagpreet
