Can someone please answer these questions. Thanks
CHEMISTRY 1 2 2 L ELECTROCHEMISTRY 2. Complete the following table for the indicated half-cell combinations at standard conditions: Toward What would Which which metal the potential Which Couples metal is the metal is the do the be under anode?cathode? electronsstandard conditions flow? Cu/Cu",Ag/Ag" Zn/Zn, Mg/Mg" Pb/Pb, Ni/Ni2+ 3. Compare the potentials you measured between the Zn/Zn2 and Cu/Cu half-cells before and after adding excess NH to the Cu/Cu half-cell. Did the potential increase or decrease? Explain the result in terms of the Nernst equation 4. Compare the potentials you measured between the Ag/Ag and Cu/Cu half-cells before and after adding excess NH,(to the Cu/Cu half-cell. Did the potential increase or decrease? Explain the result in terms of the Nernst equation (aq)
