MnO₄^- reacts with HCO₂^- to form MnO₂ and CO₃^2- in an alkaline solution. Write a balanced overall equation for the reaction.

Solution = 2MnO₄^- + 3HCO₂^- + OH^- ® 2MnO₂ + 3CO₃^2- + 2H₂O

Balance the following equations given that they occur in alkaline solutions.

a) ClO^-_(aq) + CrO₂^-_(aq) => Cl^-_(aq) + CrO₄^-2_(aq)

b) Al_(s) + NO₃^-_(aq) => Al(OH)₄^-_(aq) + NH_3(aq)

c) Cr(OH)_3(aq) + IO₃^-_(aq) => CrO₄^-2_(aq) + I^-_(aq)
