Suppose the galvanic cell sketched below is powered by the following reaction: 4 Fe(s)+2 Fe(NO a)3Fe(NO3) (aa)+3 Fe(s) E1 E2 S1 S2 Write a balanced equation for the half-reaction that happens at the cathode of this cell Write a balanced equation for the half-reaction that happens at the anode of this cell. O..e Of what substance is E1 made? Of what substance is E2 made? What are the chemical species in solution S1? What are the chemical species in solution S2?
