Answer:

Iron has a rich redox chemistry..............

Explanation:

#Fe(s) + 1/2O_2 rarr FeO(s)#

This is a very simplified representation of the oxidation of iron metal. But if there are #2.4*mol# of iron metal, it should react with #1.2*mol# of dioxygen gas to give #2.4*mol# of iron oxide, as per the stoichiometric equation.

When rust occurs on a bridge or on a steel structure, it is a surface phenomenon.
