Explanation: During the spontaneous reaction in Voltaic Cell, the balance of ions get disturb due to increase in concentration of negative charge in one half cell and positive charge in another. In order to keep balance the charges in cell, concentration of ions on both sides and overall neutrality of the system, a U-shape tube filled with inert electrolyte is connected to both half cells. The electrolyte migrates in such a way that the charges of solution in cells keep constant.
The Earth's rotation has no relation to the phases of the moon. Like everything else in the sky, the moon rises in the east just like the stars, planets, and the sun.
