Question 64

Multiple Choice

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 zinc metal immediately begins depositing electrons onto the surface of the copper, thus coating the copper with a white powder of zinc oxide, ZnO.
B) The zinc metal begins to turn a greenish color indicating the presence of the formation of cupric oxide, CuO.
C) The surface of the copper appears moist and cloudy as the zinc metal oxidizes and gets dissolved into Zinc, Zn, is more easily oxidized than copper, Cu.
