Iron is essential for the formation of hemoglobin.

About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin and in muscle cells called myoglobin.

Explanation

Iron rusts when it reacts with oxygen and water in the air, forming iron hydroxide (Fe(OH)₃).

This compound eventually dehydrates to form iron oxide, the reddish-brown rust.

Explanation

Fe3O4 occurs as a mineral with a chemical name Iron (II, III) oxide.

It is also known as Magnetite or Magnetic oxide.

Explanation

Anaemia is a condition in which the number of red blood cells capacity is not sufficient.

Iron Deficiency is the most common cause of Anaemia. 

Explanation

Iron is essential in making hemoglobin, a protein in red blood cells.

These red blood cells help carry oxygen throughout your body.
