Super Iron Batteries In 1999, scientists in Israel developed a battery based on the following cell reaction with iron(VI), nicknamed "super iron": 2 K₂FeO4(aq) + 3 Zn(s) → Fe₂O3(s) + ZnO(s) + 2 K₂ZnO₂(aq) a. Determine the number of electrons transferred in the cell reaction. b. What are the oxidation states of the transition metals in the reaction? c. Draw the cell diagram.
