1. Comment on the likelihood that the following reactions occur by a simple out-sphere electron transfer, simple atom transfer, or a multistep mechanism:

(a) HIO(aq) + I^–(aq) → I₂(aq) + OH^–(aq)

(b) [Co(phen)₃]³⁺(aq) + [Cr(bipy)₃]²⁺(aq) → [Co(phen)₃]²⁺(aq) + [Cr(bipy)₃]³⁺(aq)

(c) IO₃^–(aq) + 8 I^–(aq) + 6 H⁺(aq) → 3 I₃^–(aq) + 3 H₂O(l)

2. Complete and balance the following oxidation-reduction reactions.

a) H₂O₂(aq) → O₂(g)  (pH = 0)

b) MnO₄^–(aq) + C₂O₄^2–(aq) → CO₂(g) + Mn²⁺(aq)  (pH = 0)

c) MnO₄^–(aq) + CH₃CH₂OH(aq) → CH₃CHO(aq) + MnO₂(s)  (pH = 14)
