Explanation:
Rust is a reddish-brown colored compound which is formed by the oxidation of Iron to form ferric oxide. The formula for this chemical compound is
Oxidation is defined as the reaction in which addition of oxygen takes place.
The reaction for the formation of rust is given by the equation, we get:
By Stoichiometry,
4 moles of iron metal reacts with 3 moles of oxygen gas to form 2 moles of ferric oxide.
Hence, the correct answer is oxidation.
