Iron oxide (#Fe_2O_3#)

Explanation:

Hematite (or haematite) is an iron oxide mineral. It is made up of a repeating lattice of iron and oxygen ions. This mineral has the chemical formula #Fe_2O_3#, which is the same as that of ordinary rust. Therefore fresh samples of hematite have a rusty red appearance.
