Zinc, Zn, is more easily oxidized than copper, Cu. What happens the moment after metal strips of these metals come into contact with each other?
A. The surface of the copper appears moist and cloudy as the zinc metal oxidizes and gets dissolved into Zn(aq) ions.
B. The zinc metal begins to turn a greenish color indicating the presence of the formation of cupric oxide, CuO.
C. The zinc metal immediately begins depositing electrons onto the surface of the copper, thus coating the copper with a white powder of zinc oxide, ZnO.
D. Nothing happens. An immediate buildup of charge in either material prevents continued oxidation-reduction from occurring.
