Answers
Explanation:
Rust is an iron oxide, a usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O.
During rusting, iron combines with oxygen in the presence water. This is an oxidation reaction where oxygen acts as an oxidising agent. Since oxygen also combines with the metal iron, this is a reduction reaction, where the metal iron acts as a reducing agent.
Explanation:
Iron oxide is formed when iron and oxygen react in the presence of water or moisture in the air. Iron oxide is very common, because iron reacts easily with oxygen in the air. ... Rust occurs when iron or its alloys, such as steel, corrode.
