iron metal & oxygen combine to form magnetic oxide of iron, Fe3O4. How many mols of iron can be converted to magnetic by 8.80 mols of pure oxygen?

  • Chemistry -

    balance the equation:

    3Fe + 2O2 >> Fe3O4

    so it takes 3/2 molesFe for each mole O2

    so moles Fe=3/2 * 8.8 moles

    Writing Fe3O4 as a compound always bothers me when we know it is

    FeO.Fe2O3 an almost equal mixture of Iron(II) and Iron(III) oxides.
