Aluminum is more reactive than iron is,but iron corrodes more quickly.This occurs because
A)aluminum is reduced in the presence of oxygen while iron is oxidized.
B)aluminum develops a coating of aluminum oxide, which protects it from further reaction.
C)iron is exposed to both oxygen and water, while aluminum is rarely exposed to water.
D)iron has a lower density than aluminum does.

Question

Quizplus · Accepted Answer

Aluminum forms a protective layer of aluminum oxide when exposed to oxygen, which prevents further reaction. Iron, on the other hand, does not form a protective layer and readily reacts with both oxygen and water, leading to faster corrosion.
