Balance each of the following skeletal equations by using oxidation and reduction half-reactions. All the reactions take place in basic solution. Identify the oxidizing agent and reducing agent in each reaction.
Production of chlorite ions from dichlorine heptoxide:
Cl2O7(g) +H2O2(aq) → ClO2(^-) (aq) + O2(g)
Action of permanganate ions on sulfide ions:
MnO4(^-) (aq) + S(^2-) (aq) → S(s) + MnO2(s)
Reaction of hydrazine with chlorate ions:
N2H4(g) + ClO3(^-) (aq) → NO(g) + Cl(^-) (aq)
Reaction of plumbate ions and hypochlorite ions:
Pb(OH)4(^2-) (aq) + ClO(^-) (aq) → PbO2(s) + Cl(^-) (aq)
