Answer 1

★᭄ꦿ᭄Answer★᭄ꦿ᭄

The surface of a piece of iron will corrode first in the presence of oxygen and water. Given enough time, any piece of iron will change entirely into rust and disintegrate. The process of rusting is a combustion reaction, similar to fire. Left in contact with oxygen, iron will react with the oxygen to form rust.
