Iron II oxide: FeO
Iron III oxide: Fe2O3
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
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.
Fe3O2. But it's not right! Oxygen forms a 2- ion and iron can be 2+ or 3+. So the formulae of iron oxide can be FeO or Fe2O3.
Iron (II) oxide.FeO=====( older name still in use; ferrous oxide )
Formula of 3 types of Iron oxides: Iron(II) oxide= FeO Iron(III) oxide= Fe2O3 Iron(II,III) oxide= Fe3O4
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)
The chemical formula for iron (lll) oxide is Fe2O3.
The chemical formula for iron (III) oxide is Fe2O3, where Fe represents iron and O represents oxygen.
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 formula for Iron (III) oxide is Fe2O3. This compound is also known as ferric oxide and is commonly found in rust.
IOU 1 answer ;)See this:anhydrous-iron-oxide
The formula for iron (III) oxide is Fe2O3 and the formula for carbon dioxide is CO2. Therefore, the combined formula for iron (III) oxide and carbon dioxide is 2Fe2O3 + 3CO2, which indicates the reaction between them or the product formed.
Iron reacts with oxygen to form iron oxide. The chemical formula for iron oxide is Fe2O3 (rust) or Fe3O4.
There are a number of compounds of iron wuth oxygen, iron(I) oxide, ferrous oxide, FeO iron (II,III) oxide ferric ferrous oxide, Fe3O4 iron(III) oxide, ferric oxide, Fe2O3.
