What happens to a redox reaction when it is shown as half-reactions?
Well, not much.........
Our goal is to provide a stoichiometrically balanced equation that accurately represents the macroscopic chemical change that takes place, and our method of breaking out oxidation and reduction equations to represent the overall chemical reaction is merely a means to that end.
All chemical reactions conserve mass and charge, so our use of electrons helps us to represent this conservation of charge:
I admit that assigning oxidation numbers, representing the loss and gain and electrons, and both of these are highly conceptual entities, may seem a bit abstract, but in the end, it provides us with an equation that represents gross chemical transfer.
Is charge and mass balanced? Is this a problem for you?

When a redox reaction is shown as half-reactions, it separates into two parts: oxidation and reduction. The oxidation half-reaction involves the loss of electrons, while the reduction half-reaction involves the gain of electrons.

When a redox reaction is shown as half-reactions, it is split into two separate reactions: oxidation and reduction. In the oxidation half-reaction, the reactant that loses electrons (oxidized) is represented, while in the reduction half-reaction, the reactant that gains electrons (reduced) is represented. This separation allows for a clearer understanding of the electron transfer process involved in the redox reaction. Additionally, balancing each half-reaction individually makes it easier to balance the overall redox reaction by ensuring that the number of electrons lost in the oxidation half-reaction equals the number of electrons gained in the reduction half-reaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
