The mineral form of iron II oxide is known as wüstite. Hematite (69.9% Fe) and Magnetite ( 72.4% Fe) are two other examples of iron oxide. Magnetite has naturally high iron content than Hematite.
iron-to-oxygen ratios of
Hematite
3.79 g of Fe and 1.63 g O
and
Magnetite
22.8 g Fe and 8.70 g O
where Fe symbolise iron and O symbolise oxygen.
Answer:
Magnetite- 3:4
Hematite-2:3
Explanation:
Hematite is an ore of iron. Its chemical formula is Fe₂O₃. It means there are 2 iron atoms per 3 oxygen atoms. The ratio of iron-to-oxygen is 2:3.
Magnetite is also an ore of iron. Its chemical formula is Fe₃O₄. It means there are 3 Iron atoms per 4 oxygen atoms. The ratio of iron-to-oxygen is 3:4.
