Question 1

Based on the following information,

F₂(g) + 2 e^-→ 2 F^-(aq) E° = +2.87 V
Li⁺(aq) +   e^-→   Li(s) E° = -3.04 V

which of the following chemical species is the strongest reducing agent?
◦ F₂(g)
◦ Li⁺(aq)
◦ F^-(aq)
◦ Li(s)

Question 2

Calculate E_cell at 25 °C for the following voltaic cell. K_sp for NiCO₃(s) is 1.42 × 10^-7.

Ni(s) Ni²⁺(aq) [sat'd NiCO₃(s)] Ni²⁺(aq) (0.010M) Ni(s)

The half-reaction is:  Ni²⁺(aq) + 2 e^-→ Ni(s)  E° = -0.257 V
◦ +0.257 V
◦ -0.257 V
◦ 0.000 V
◦ +0.0844 V
◦ +0.0422 V
