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)
Iron II oxide: FeO Iron III oxide: Fe2O3
We know that iron (Fe) and oxygen (O) make up iron oxide. (There is more than one oxide of iron, by the way.)
FeO is iron(II) oxide, also known as ferrous oxide, where iron has a +2 oxidation state. Fe2O3 is iron(III) oxide, also known as ferric oxide, where iron has a +3 oxidation state. This means FeO has one iron atom for each oxygen atom, while Fe2O3 has two iron atoms for every three oxygen atoms.
Iron(II) oxide is FeOIron(III) oxide is 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)
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, Fe3O4, and Fe2O3
When iron is burnt (heated) and exposed to air the iron will combine rapidly with oxygen atoms to form FeO molecules (FeO - Iron Oxide - Also known as 'rust' on iron materials)
The name of the compound Fe3O4 is called iron (II,III) oxide. (Wikipedia)
Iron oxide is too general a term. The formula for Iron (II) Oxide is FeO and the formula of Iron (III) Oxide is 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.
FeO for ferrous oxide, ( iron(II) oxide); Fe2O3 for ferric oxide, (iron(III) oxide) and Fe3O4 for ferrous ferric oxide, (iron (II,III) oxide)
Iron II oxide: FeO Iron III oxide: Fe2O3
Fe(OH)2 is called "Iron (II) hydroxide". If you look in older references, you will find it called "Ferrous hydroxide". (There is no stable chemical compound FeOH2)
