The diagrams above illustrate the equipment used to electroplate four identical objects with silver or zinc. The table provides the conditions used. Which of the following provides the basis for the identification of the object that requires the highest current, I, to complete the electroplating? A. Object 1, based on the molar mass of Ag and the time of operation. B. Object 2, based on the molar mass of Ag and the time of operation. C. Object 3, based on the coulombs of charge needed and the time of operation. D. Object 4, based on the coulombs of charge needed and the time of operation.
