What is the formula for iron 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

Iron II oxide: FeO Iron III oxide: Fe2O3

The formula for iron (III) oxide is Fe2O3.

The formula of iron oxide is Fe2O3.

FeO (iron II or ferrous oxide) , Fe2O3 (iron III or ferric oxide)

Hæmatite, is the mineral form of Iron (III) oxide The formula for Iron (III) oxide is Fe2O3

The chemical formula for iron (lll) 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 answer is FeO, not to be confused with Iron III oxide (Fe2O3).

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.

The chemical name for rust is Iron Oxide. The formula for Iron Oxide (rust) is FeO.

The iron oxide with the formula F3O4, called iron (II,III) oxide, is known as magnetite. There are also iron (II) oxide, FeO, and iron (III) oxide, Fe2O3, but they are not magnetite.

Iron (II) oxide. FeO =====( older name still in use; ferrous oxide )

Pure iron oxide is a compound, but if there is something else mixed in with it, then of course it will become a mixture. There is more than one oxide of iron, though. Here are 2 types of iron oxide: Iron (II) Oxide is a black powder with a formula of FeO Iron (III) Oxide, also rust, is a brownish-red powder with a formula of Fe2O3

Fe(III) oxide formula: Fe2O3

Fe2O3 or iron(iii) oxide

Iron(II) oxide is Fe(OH)2 Iron(III) oxide is Fe(OH)3

The formula for iron (II) oxide is FeO. It is a black colored powder, not rust.

There are a number of chemical compounds conmade up from iron and oxygen Iron(III) oxide, ferric oxide, is Fe2O3 Iron(II)oxide, ferrous oxide, FeO iron(II,III) oxide, ferrous ferric oxide, Fe3O4

If the chemical formula is Fe3O4, then there are 3 iron atoms.

Fe2O3 ---------

Iron II oxide has the formula unit of FeO.

The formula for iron (III) oxide is FeCl3, whether the formula is in a balanced equation or anywhere else where the formula is properly used.

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.
