Galvanic Cell

Q. 18. You got caught in a storm while sailing your boat and have been stranded on an island that has no cell reception. You need to construct a voltaic cell to replace your boat radio's batteries. You have metal pieces from your boat, and need 1.5 V to power the radio. If coconuts from the island are capable beakers and sea water is a terrific electrolyte, which of the following pieces need to be used to construct your voltaic cell (assuming standard conditions)? Show your work and draw the voltaic cell: label the cathode and anode, each metal, and the solutions.
