Actually, the answer is "yes" and "no." The surface of the iron is covered in rust, which FeO(OH), which is obviously not pure iron. (When FeO(OH) forms in nature, the mineral is called goethite.) The iron underneath the rust is still iron. Remove the rust and you're back to "pure" iron.
Formation of rust ..... the formation of rust requires iron, oxygen and water.
4Fe(s) + 3O2(g) + 2H2O(l) --> 4FeO(OH)(s)
Some people erroneously write a reaction for the formation of rust as:
4Fe(s) + 3O2(g) --> 2Fe2O3(s)
That equation works nicely for the combustion of iron (yes, iron will burn), but Fe2O3 is not rust, and the formation of rust requires water.
