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 + I₂ 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 + I205 → CO₂ + I2 9. 2 Fe ³+ (aq) + Sn²+ (aq) → 2 Fe ²+ + Sn¹+ (aq) 10. Chlorine gas oxidises Fe 2+ ions to Fe³+ ions. In the process, chlorine is reduced to chloride ions.
