1. Balance the following oxidation-reduction reactions using thehalf-reaction method and tell the number of electrons transferredin 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) basicsolution
c) Sb(s) + H2SO4(aq) --->Sb2(SO4)3(s) + SO2(g)acidic solution
d) H2O2(aq) +MnO4-(aq) ---> MnO2(s) +O2(g) basic solution
