WebIron reacts with oxygen in the air to form various oxide and hydroxide compounds; the most common are iron (II,III) oxide (Fe 3 O 4) and iron (III) oxide (Fe 2 O 3 ). Iron (II) oxide also exists, although it is unstable at room temperature. These oxides are the principal ores for the production of iron. WebStep-by-step explanation.
