Question 2
Copper atoms have a greater tendency to be reduced than iron atoms do. Was this good news or bad news for the Statue of Liberty, whose copper exterior was originally held together by steel rivets?
A) This was good news since the steel rivets prevented the copper from eroding.
B) Electrons will preferentially flow from the iron to the copper and then onto oxygen. Corrosion is thus accelerated around the interface of these two metals.
C) This combination of metals have no effect on each other and that is why engineers chose to use them together.
D) This combination of metals caused the copper to oxidize and turn green.
