Short Answer Section. Place all final answers in the box. 15. The following is representation of a galvanic cell Voltage iri Fe Al KNO AINO,), (aq) Fe(NO,), (aq) A Indicate which electrode is the cathode and which elecerode is the anode A. Indicate which electrode is the cathode and which electrode is the anode. Anode: Cathode: B. Write the line diagram for this cell. 16. Refer to the energy diagram below. In the corresponding box on the right, write the numbered process that may occur after a molecule absorbs an ultraviolet or visible photor

Explanation / Answer

Solution.

In a galvanic cell, the negative electrode is Anode and the positive electrode is Cathode. Therefore, Al electrode is the Anode and Fe electrode is the Cathode.

In the line diagram representation of a cell, Cathode is always the right electrode and Anode is always the left electrode:

Al(s) | Al(NO3)3(aq) || Fe(NO3)2(aq) | Fe(s) .
