Question:

a. Write two half-equations for the following reactions. For each half-equation state whether oxidation or reduction is occurring.

i. Cl₂ + 2I^– → I₂ + 2Cl^–

ii. 2Mg + O₂ → 2MgO

iii. 4Fe + 3O₂ → 2Fe₂O₃

b. Zinc metal reacts with IO₃^-ions in acidic solution. Construct a balanced ionic equation for this reaction, using the two half-equations below:

2IO₃^- +12H⁺ + 10e^– → I₂ + 6H₂O

Zn → Zn²⁺ + 2e^–
