Answer:
See explanation
Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
Well what I notice right here. He correct, because if the moon is completely dark that is called a new moon. Its fine really! The moon is away from the sunlight so if its rotating and its not from the sun its just a new moon. And the OTHER side is showing brightness. I hope this helpsss!

Answer:
change within a cell
Explanation:
In biology, depolarization is a change within a cell, during which the cell undergoes a shift in electric charge distribution, resulting in less negative charge inside the cell. Depolarization is essential to the function of many cells, communication between cells, and the overall physiology of an organism.
