For each of the following balanced oxidation-reduction reactions, (i) identify the oxidation numbers for all the elements in the reactants and products and (ii) state the total number of electrons transferred in each reaction. Only need to know the total number of electrons transferred in each! Thank you!

I2O5(s)+5CO(g)→I2(s)+5CO2(g)

2Hg2+(aq)+N2H4(aq)→2Hg(l)+N2(g)+4H+(aq)

3H2S(aq)+2H+(aq)+2NO−3(aq)→3S(s)+2NO(g)+4H2O(l)

Only need to know the total number of electrons transferred in each! Thank you!

Hi, the following problem I'm working on is: The hydroperoxide ion HO2- (aq) reacts with permanganate ion MnO4- (aq) to produce MnO2(s) and oxygen gas. Balance the equation for the oxidation of hydroperoxide ion to O2(g) by permanganate ion in a basic solution. I know the beginning equation is: HO2^-(aq) + MNO4^-(aq) ---> MnO2(s) +O2(g) and that I have to write half rxns for each one. I also know the answer ends up being: H2O(l) + 2MnO4- (aq) +3HO2-(aq) --->...
