15. Solving a chemistry problem

96. Write the equations of redox reactions occurring on the electrodes in a galvanic cell and calculate its EMF.
Galvanic cell Mg/Mg2+||Ag+ /Ag.
Concentration [Mg2+]=10-2 mol/l. Concentration [Ag+]=10-2 mol/l.
2. Write the equations of the anodic and cathodic processes during the electrolysis of an aqueous solution of the ZnCl2 salt with an inert and soluble Zn anode. What substances and in what quantity are released on the cathode and inert anode during the electrolysis of a given aqueous salt solution at I=13.4 A and t=2 h.
3. Write the reaction equation and the processes that occur during corrosion on the anode and cathode in an HNO3 solution of a plate of Fe coated with another metal (Hg), if the coating is broken and contact with acid is possible. Determine the type of coating (anodic or cathodic).
