By the way, it's either FeO, Fe2O3, or Fe3O4. In the case of water as a catalyst, the intermediaries between Fe and it's oxides are Fe(OH)2 and Fe(OH)3, respectively. Also, the FeO becomes Fe2O3 upon further oxidation and a mixture of FeO and Fe2O3 partially becomes Fe3O4 upon further oxidation. If the Fe is oxidized in an Earth-like atmo (21% O2 (Oxygen dimer)), then the main product is Fe2O3 (Iron(III) Oxide). If oxidized in a low-O2 atmo, the main product is FeO (Iron(II) Oxide). If oxidized in a high-O2 atmo, the main product will be Fe3O4 (Iron(II,III) Oxide). If in a Earth-like or low-O2 atmo, Fe3O4 will eventually break down into FeO and Fe2O3 and, if in a Earth-like atmo, the FeO will eventually oxidize to Fe2O3.
Haha! Iron(II) Oxide is "ugly"!
