Part B
The half-reactions that occur in ordinary alkaline batteries can be written as
Cathode : MnO2 (s) + H20 (1) +e+MnO (OH) (s) + OH (aq)
Anode : Zn (s) + 20H (ag) →Zn(OH), (s) + 2e
In 1999, researchers in Israel reported a new type of alkaline battery, called
a "super-iron" battery. This battery uses the same anode reaction as an
ordinary alkaline battery but involves the reduction of FeO ion (from
K2FEO4) to solid Fe(OH), at the cathode.
Write a balanced equation for the cathode half-reaction in a super-iron battery. The half-reaction
occurs in a basic environment.
O Fe(OH): (s) + 50H-(ag)→FE0- (ag) + 4H2O(1) + 3e-
O FeO; (aq) + 4H2O(1) + 3e →Fe(OH);(8) + 50H (aq)
O FeO (aq) + H2O(1) + 3EFE(OH) (s) + OH-(aq)
O FeO (ag) + 2H2O(1)+ 3eFe(OH);(s) + 20H (aq)

Part C
A super-iron battery should last longer than an ordinary alkaline battery of the same size and
weight because its cathode can provide more charge per unit mass. Quantitatively compare the
number of coulombs of charge released by the reduction of 11.2 g of K2FEO, to Fe(OH), with
the number of coulombs of charge released by the reduction of 11.2 g of MnO2 to MnO(OH).
