Answer to Question #330859 in General Chemistry for gel

Question

Write the oxidation half-reaction and reduction half-reaction, and shorthand electrochemical notation for the following.

1. Mg+H^+ -> Mg^ 2+ +H 2

2. KI + Cl2 -> KCl + I2

3. Cr^ + +Sn^ 4+ Cr^ 3+ +Sn^ 2+

4. 3 Hg^ 2+ +2 Fe (s) 3 Hg 2 +2 Fe^ 3+

5. 2 As (n) + 3 Cl₂ (g) → 2 AsCla

6. NaBr + Cl₂ ⇒ NaCl + Br₂

7. F*e_{2}*O_{3} + CO -> Fe + C*O_{2}

8. CO + I_{2}*O_{5} -> C*O_{2} + I_{2}

2 Fe^ 3+ (aq) +Sn^ 2+ 2 Fe^ 2+ +Sn^ 4+ (aq)

10. Chlorine gas oxidises Fe2+ ions to Fe³+ ions. In the process, chlorine is reduced to chloride ions.
