Galvanic Cell (Simplified) Practice Problems

An electrochemical cell uses the following reaction:
Fe(s) + Pb²⁺(aq) → Fe²⁺(aq) + Pb(s)

Make a sketch representing the cell after a substantial amount of electrical current has been generated. 

Identify the cathode in the electrochemical cell shown below

Identify which of the statements below is true.

Consider the following redox reaction:

2 Ag⁺_(aq) + Cu_(s) → 2 Ag_(s) + Cu²⁺_(aq)

Sketch a Galvanic cell that employs the following redox reaction and show which ions are present in each solution. Identify the electrodes as cathode and anode and write oxidation and reduction half-reactions. Finally indicate the electron flow direction for this cell.
