Answer to Question #185598 in General Chemistry for Aich80

Question

Analyze each cell reaction. Identify and write the half-reaction that occurs in the anode and in the cathode. Calculate the standard cell potential.

1. Li (s) + F₂ (g) = Li⁺ (aq) + 2F^- (aq)

2. Au³⁺ (aq) + Co(s) = Au(s) + Co²⁺ (aq)

3. 2 Al (s) + 3 i₂ = 2 Al⁺³(aq) + 6 i^-1 (aq)

4. F₂ (g) + 2Cl^-1 (aq) = 2F^-1 (aq) + Cl₂ (g)

Answer 1

$Zn(s) = Zn_2^+ (aq) + (2e^-).$
