IOU 1 answer ;)See this:anhydrous-iron-oxide
Iron II oxide: FeO Iron III oxide: Fe2O3
There is more than one oxide of Iron, to answer your question you need to be more specific with which oxide you are asking about.
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
The chemical formula for iron (lll) oxide is Fe2O3.
Iron oxide is too general a term. The formula for Iron (II) Oxide is FeO and the formula of Iron (III) Oxide is Fe2O3
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
The chemical formula for iron(III) oxide is Fe2O3. This indicates that each iron atom is bonded to three oxygen atoms in the compound.
The formula of two iron (Fe) and three oxygen (O) atoms would be written as Fe2O3. This compound is known as iron(III) oxide or ferric oxide.
The chemical formula for Iron III oxide is Fe2O3. It is composed of two iron atoms bonded to three oxygen atoms in a compound.
The chemical formula for iron (lll) oxide is Fe2O3.
