Consider the redox reaction: H₂ + Cl₂ → 2HCl. Identify the half-equations for the oxidation and reduction processes.
💡 Hint: Start by identifying what is being oxidized and reduced.
You have the reaction 2MnO₄⁻ + 10e⁻ + 16H⁺ → 2Mn²⁺ + 8H₂O. Show how to derive this from half-equations.
💡 Hint: Remember to find the half-equations first.
