The fаmоus Prоfessоr on the 1960s sit-com Gilligаn s Islаnd once constructed a series of voltaic cells in one episode to use as a substitute for their radio s dead batteries. A single D-cell has an emf of 1.5 V. Identify which scraps of metal from their damaged boat, the Minnow, could be used to create a 1.5 V voltaic cell. Assume that the Professor brought his chemistry set along on the three-hour tour, and in it he has nitrate salts of all of these metals to complete the half-cells. Also assume that coconuts make great beakers and that seawater is a terrific electrolyte solution for a salt bridge. Use the Eo from the table provided
