Answer: rust is the coating which is formed on iron and steel when they come into contact with o2 co2 and h2o.
Explanation: this is because of a corrosive reaction formed when these three elements react with iron. this weakens iron and causes it degrade in quality. IT IS NECESSARY for oxygen, carbon dioxide and water/ moisture to be present for rusting
