4.129. An Iron Battery A prototype battery based on iron compounds with large, positive oxidation numbers was developed in 1999. In the following reactions, assign oxidation numbers to the elements in each compound and balance the redox reactions in basic solution. a. FeO2 (aq) + H₂O(l) → FeO(OH)(s) + O₂(g) + OH(aq) b. FeO2 (aq) + H₂O(l) → Fe₂O3(s) + O₂(g) + OH(aq)
