Please give me three reactions and the delta H of each...
or better yet please write out the steps of Hess's law...

You want to look up the enthalpies of formation of C2H5OH (x 2), CO2 (x 2) and C6H12O6. You will find that they all combine nicely in a Hess Cycle!

Enthalpy of fermenation = the first two I've mentioned minus the last one.
