Requesting help balancing yellow iron oxide thermite equation

[Timm]

I would appreciate it if someone would help me calculate out (show me how, anyway, was never great at algebra..) the stoichiomemetric difference between standard red iron oxide and this fine yellow spanish iron oxide i've aquired.. which I understand to be Fe2o3*H20, or something close to that.. And how the latter might react with aluminum or magnesium in a Goldschmidt-type reaction. Where does the hydrogen go?

I believe that it is close to the same as the red. I would sub it 1-1. Should not be a prob to make the Goldschmidt type thermite ..
