Contrary to potential appearance, this is not homework. I've been out of college for a long time now. Just working on a project with my kids and I'm trying to approach specific energy of these reduction reactions from the theoretical side, mostly so I know what sort of safety precautions to take. I can balance the equations and find the bond energies and all that stuff to get an idea of reaction chemistry and specific energy, but only if I already know both sides of the equation. Here are the reagents I'm looking at: Na2S2O5 + KNO3 → ? Na2S2O5 + KNO3 + Fe2O3 → ? Na2S2O5 + KNO3 + C12H22O11 → ? KNO3 + C12H22O11 → ? KNO3 + C12H22O11 + Fe2O3 → ? Na2S2O5 + KNO3 + C12H22O11 + Fe2O3 → ? I know that Na2S2O5 + KNO3 can react to form Na2S04 + KNO + S03 and that KNO3 + C12H22O11 will produce CO2 and H2O but I don't know exactly where the potassium and nitrogen end up in the latter reaction. I suspect that the water and sulfur trioxide could then react as well, though I don't know whether the sulfur would act to poison the other parts of the reaction. And I have no idea what the Fe2O3 would do to it all. And before anyone asks: yes, I know that numerous sulfur oxides and a lot of other potential byproducts are toxic. Necessary precautions will be taken.
