116. Solving a chemistry problem

302. For the proposed galvanic cells, calculate the electrode potentials and EMF. If the concentration of the solution is not indicated, take the potential as standard (Table A.6). Write the equations of the anodic and cathodic processes, the molecular equation of the current-generating reaction, draw up a diagram and indicate the directions of movement of electrons and ions.
