100. Solving a chemistry problem

Write down the electrolysis reactions on inert electrodes and calculate the mass of the substance obtained at the cathode and the volume of gas released at the anode during the electrolysis of electrolyte solutions, if the electrolysis time is 20 minutes, and the current strength is I \u003d 2A, if the current output is W \u003d 100%. What substances will be released on the electrodes when replacing an inert anode with a metal anode specified in the task?

Electrolyte Metal electrode
KNO3 Cu
