Direction: Write the oxidation half-reaction and reduction half-reaction, and shorthand electrochemical notation for the following. 1. Mg + H+ → Mg2+ + H₂ 2. KI + Cl₂ KCl + 1₂ 3. Cr+ + Sn4+ → Cr³+ + Sn²+ 4. 3 Hg₂+ + 2 Fe (s) - 3 Hg₂+2 Fe³+ 5.2 As (s) + 3 Cl₂ (g) → 2 AsCl3 6. NaBr + Cl₂ → NaCl + Br2 7. Fe2O3 + CO → Fe + CO₂ 8. CO + 1₂05 CO₂ + I₂ 3+ 9.2 Fe ³+ (aq) + Sn²+ (aq) → 2 Fe ²+ + Snª*(aq) 2+ ions to Fe³+ ions. In the process, chlorine is reduced to 10. Chlorine gas oxidises Fe chloride ions.
