QUESTION

Table 1 : Potentials Combination anode Cathode Voltage ( V ) CU and My My CU 1. 640 CU and In Zn CU 7. 04 My and Ni Mg Ni 1. 665 Ni and Zn Ni 0. 935...

4) In Part A and B of this experiment the half reactions were isolated in different wells. In Part C the oxidation and reduction half reactions occurred in the same well. Why was this possible?

First table is Part A

5) Effect of Composition on Band Gap: How does voltage and color change going from LEDs with the highest phosphorous percentage to the lowest? Explain your data in terms of band gap energy. As part of your explanation, rank the LEDs in order of increasing band gap energy (lowest to highest).

I have no Idea how to solve this two problems. Help me to get into the answer. These are lab experiment question.
