Question

given an example of an oxidation reactions

Answer 1

 When the soft insides of fruit are exposed to oxygen in the air, they become oxidized, causing them to break down and turn brown. The process is very similar to rusting; oxygen steals electrons from atoms and compounds. The unoxidized form of these compounds is different from the oxidized form that is, unfortunately, unappealing to eat.

Answer 2

Fe(s) + O₂(g) = Fe₂O₃(g)
