113. Solving a chemistry problem
152. Electrolysis of a CuSO4 solution was carried out for 15 minutes at a current strength of 2.5 A. 0.72 g of copper was released. Make up the electronic equations of the processes occurring on the electrodes in the case of a copper and carbon anode. Calculate the current output (the ratio of the mass of the released substance to the theoretically possible).
