The following diagram represents a cell in which two different metals are placed in their respective ion solutions and hooked up with an external circuit. 14 Which of the following combinations of metal/metal ion half-cells would produce the highest reading on the voltmeter? Select one: cadmium / cadmium ion half-cell and copper / copper ion half-cell O lead / lead ion half-cell and zinc/zinc ion half-cell nickel/nickel ion half-cell and zinc/zinc ion half-cell lead / lead ion half-cell and silver/silver ion half-cell Use the following information to answer the next 2 questions. Fig. 2 As the cell in figure 2 operates, the cations move towards the Select one: O Zn electrode, which loses mass. O Zn electrode, which gains mass. Pb electrode, which loses mass. Pb electrode, which gains mass. As the cell in figure 2 operates, the electrons flow towards the Zn Porous Barrier 1.0 mol/L Zn(NO₂), 1.0 moit. Pb(NO₂), electrode and the cell voltage -Pb 0 over time.
