Template for calculating the ΔH° in a multiple step chemical reaction
... total ΔH° =_________ Write the two steps in the proper order... How to do it... To make Al2O3, you need the O3 from Fe2O3. To do that, you must first carry out the process of breaking up the Fe2O3, which has its own enthalpy of formation. However we are not forming Fe2O3. We are decomposing it. So, ...
