34. Solving a chemistry problem

There are two electrodes:
Electrode A
Electrode type Electrolyte concentration, mol/l gas pressure p
Pt,H2|HCl c=0.1 p=1.3 atm

Electrode B
Electrode type Electrolyte concentration, mol/l
CrCl3|Cr 0.1
Necessary:
1) name what type each electrode belongs to;
2) make a correctly open galvanic cell from these electrodes (write down the circuit of the galvanic cell);
3) Write down the electrode reactions and the final reaction in the galvanic cell
4) write down the Nernst equation for calculating the EMF;
5) Find the standard EMF, the activity potential of the determining ions.
6) Calculate the electromotive force of the galvanic cell.
