1. Balance the following oxidation-reduction reactions using the half-reaction method and tell the number of electrons transferred in the balanced oxidation-reduction reaction
a) S2-(aq) + NO3-(aq) ---> S8(s) + NO2(g) acidic solution
b) MnO4-(aq) + I-(aq) ---> MnO2(s) + IO3-(aq) basic solution
c) Sb(s) + H2SO4(aq) ---> Sb2(SO4)3(s) + SO2(g) acidic solution
d) H2O2(aq) + MnO4-(aq) ---> MnO2(s) + O2(g) basic solution
