What occurs when iron and oxygen combine to form iron oxide?

Answer 1

Basically there are 2 forms of iron:iron 2+ and iron 3+

Iron 2 oxide, basically is Fe2+ in order to stabilize it you need 2- which is exactly one oxygen ion

therefore we get FeO

While iron 3 oxide is Fe3+ in order to make a stable compound we need 2 Fe 3+ along with 3 O 2-

which gives us +6 and -6 therefore a stable compound which is Fe2O3

the hydrated form of iron 3 oxide is rust

Answer 2

The reaction which occurs between iron and oxygen is an oxidation-reduction reaction. Iron is oxidized, as it loses electrons, while oxygen is reduced because it gains electrons. The result is various iron oxides, commonly known as rust.

Answer 3

It depends which iron oxide you mean. Iron(II) Oxide, FeO, which is black and has 1 oxygen molecule bonded with an iron one . Iron(III) Oxide (Fe2O3) ie rust has 2 iron molecules bonded to 3 oxygen molecules.

Answer 4

Fe + O = FeO iron II oxide

But Fe with O as Fe2O3 is iron III oxide which is rust.

Answer 5

iron-oxide

Common name- rust.

Answer 6

Those are known as iron oxides. Some of them are hematite and magnetite.

Answer 7

The iron oxides FeO, Fe2O3 , Fe3O4

Answer 9

Oxidation (or in common terms rusting)
