Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
The raw materials needed for making iron are iron ore, coke (a type of coal), and limestone. Iron ore is the primary source of iron, coke is used as a fuel and reducing agent, and limestone helps to remove impurities during the smelting process.
Iron is needed to produce iron sulphate.
Iron and oxygen are needed for iron to rust. When iron is exposed to moisture and air, a chemical reaction occurs where the iron oxidizes to form iron oxide, which is known as rust.
Iron is needed to make haemoglobin, the protein in red blood cells that carries oxygen throughout the body. Without enough iron, the body cannot produce adequate haemoglobin, leading to a condition called iron-deficiency anemia.
