Answer:
Your question is incomplete.
But what I can help you with is once a redox reaction occurs, one element oxidizes and another is reduced, generating the equilibrium of the reaction.
On the other hand, it is important to clarify all the redox reactions, reactions of reducing factors (positive protons) and oxygen that oxidize.
Explanation:
example:
Reduction half-reaction: {2 e ^ - + Cu ^ 2 + -> Cu} {2 e ^ - + Cu ^ 2 + -> Cu}
Half oxidation reaction: {Fe -> Fe ^ 2 + + 2 e ^ -} {Fe -> Fe ^ 2 + + 2 e ^ -}
or more frequently, also called general equation:
{Fe + Cu ^ 2 + -> Fe ^ 2 + + Cu} {Fe + Cu ^ 2 + -> Fe ^ 2 + + Cu}
