104. Solving a chemistry problem

For a given galvanic pair of elements:
Al│Al3 (10-2mol/l)║Ag (10-1mol/l)│Ag
- identify the anode and cathode;
-write the equation of the processes occurring at the anode and cathode in a working galvanic cell. Write down the equation of the current-generating reaction;
-calculate the EMF of a galvanic cell;
-in what direction will the electrons move in the external circuit during the operation of this galvanic cell.
