Answer 2

Answer:

(1) The combination of oxygen with a substance forming oxide. (2) A chemical reaction in which there is the loss of electrons or gain (or increase in the proportion) of oxygen, hence, resulting in an increase in oxidation state by a molecule, atom or ion.

A classic example of the old definition of oxidation is when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is: 2 Fe + O2 → Fe2O3. The iron metal is oxidized to form the iron oxide known as rust.
