1. One of the half-reactions for the electrolysis of water is

2H₂O(l) →O₂(g) + 4H⁺(aq) + 4e⁻

If 0.992 L of O₂ is collected at 25°C and 755 mmHg, how many faradays of electricity had to pass through the solution?

What is E°_cell for the following reaction?

2 Ag(s) + Sn²⁺(aq) → 2 Ag⁺(aq) + Sn(s)

Ag⁺(aq) + e^– → Ag(s)	E° = 0.80 V
Sn⁴⁺(aq) + 2e^– → Sn²⁺(aq)	E° = 0.13 V
Sn²⁺(aq) + 2e^– → Sn(s)	E° = –0.14 V

+0.94 V

–0.94 V

+0.67 V

–0.67 V

+1.34 V

3. One of the half-reactions for the electrolysis of water is

2H⁺(aq) + 2e⁻ →H₂(g)

If 0.845 L of H₂ is collected at 25°C and 782 mmHg, how many faradays of electricity had to pass through the solution?
