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)
Iron oxides are formed, such as: iron(II) oxide (FeO), iron(II,III) oxide (Fe3O4), iron(III) oxide (Fe2O3)
Two possibillities: ferrous and ferric oxide: FeO and Fe2O3 respectively (or mixtures of them)
This compound is the iron(III) oxide, Fe2O3.
The iron oxide - Fe2O3.
iron oxide
carbon dioxide
Magnesium oxide?
Iron oxide (ferric oxide)
FeSe
By rusting hydrated iron(III) oxide is formed.
This compound is the iron(III) oxide, Fe2O3.
carbon dioxide
Is it Solid?
The chemical formula for the compound formed between iron(III) and iodine is FeI3 (iron(iii) iodide).
This compound is iron(II) iodide - FeI2.
Cooper get oxidised to copper oxide when burned in air.
Magnesium oxide?
Iron oxide (ferric oxide)
Water (H2O) is formed when hydrogen is burned by oxygen
Nothing , because both are solid and unreactive but when sulphur is put in molten iron the iron sulphide FeS is formed.
