Explain balancing redox reactions as you would to a capable student, in 3-4 sentences.

To balance a redox reaction, first identify what's being oxidized (losing electrons) and what's being reduced (gaining electrons), then split the reaction into two half-reactions. Balance each half-reaction separately: first balance the main atoms, then add H₂O to balance oxygen, H⁺ to balance hydrogen (or OH⁻ in base), and finally add electrons to balance the charge. Once both half-reactions are balanced, multiply them by appropriate factors so the electrons cancel out when you add them back together, giving you the balanced overall equation. The key insight is that the total electrons lost must equal the total electrons gained.
