Difference Between Fe2O3 and Fe3O4 - _

Fe3O4; .... . · . . FeO B FeO2 The natural form of this mineral is magnetite.There are many physical and structural difference between Fe 2 O 3 and Fe 3 O 4. The main difference between Fe 2 O 3 and Fe 3 O 4 is that Fe2O3 is a paramagnetic mineral having only Fe2+ oxidation state whereas Fe3O4 is a ferromagnetic material having both Fe2+ and Fe3+ oxidation states. Key Areas Covered 1. What is Fe 2 O 3How much of that is Fe? Divide the second value by the first to find the fraction of Fe in FeO. Multiply by 100 for percentage. Rinse and repeat for Fe2O3 and Fe3O4. And for the percentage of S in H2SO4. And the percentage of O in H2O. And for any element in any compound you could ask about.
