The strongest oxidizing agent of them is FeO4-2 ion, which is called Ferrate.
Its oxidizing powers come from Iron in its +6 oxidation state. These ions are even stronger oxidizers than Permanganates or Nitrates.
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
These compounds are iron oxides as FeO, Fe2O3, Fe3O4.Rust.
Fe3O4 is the mineral magnetite, with aproper chemical name of Fe(II, III) oxide. it exhibits ferrimagnetism. It has iron atoms as FeII and FeIII. An old way of writing it was FeO.Fe2O3 The balanced equation for production from the elements is :- 3Fe + 2O2 -> Fe3O4 Commercially it is made by for example redung Fe2O3 with CO 3Fe2O3 + CO = 2Fe3O4 +CO2
3Fe + 4(H2O) ---> Fe3O4 + 4(H2) You really should learn this, its not that hard =D
This is an especially complicated valency problem, because Fe3O4 is a combination of Fe2O3 and FeO. As usual, except in peroxides and superoxides, oxygen is assigned a valency of -2. This means that the iron in Fe2O3 has a valency of +3 while the iron in FeO has a valency of +2. (Note that these two oxides of iron also occur separately from each other, as well as in Fe3O4.) Therefore, the average valency of iron in Fe3O4 is 8/3, a rare example of fractional valency made possible only by the fact that iron in this compound actually exists in two integral valence states in the same compound.
FeO, Fe2O3, Fe3O4 Note: Fe3O4 can be considered as a mixture of FeO and Fe2O3

Fe3O4 is not a pure compound...it is a mixture of FeO and Fe2O3 Assuming 100% yield in converting to all Fe2O3 4.05 mole x 2/3 = 2.7 mole

FeO, Fe3O4, and Fe2O3
Hematite is an oxide of iron in its "raw" or "natural" form. It's a mineral, and it's iron(III) oxide. Its formula is Fe2O3.Hematite is Fe2O3.
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
just apply poac on both the sides and get the solution
There are at least three different iron oxides, with formulas FeO, Fe2O3, and Fe3O4. The equations are: FeO + Ca = CaO + Fe Fe2O3 + 3Ca = 3CaO + 2Fe Fe3O4 + 4Ca = 4 CaO + 3Fe
These compounds are iron oxides as FeO, Fe2O3, Fe3O4.Rust.
