8 23. Complete the following tasks for the transition metal complexes listed below: [Fe(CN) 3 (en)CO] - and [FeBr 4 (NH 3 ) 2 ] 2- a) Provide the coordination number for each complex. b) Determine the hybridization state of iron. c) Give the molecular shape for each complex. d) Label each complex as either paramagnetic or diamagnetic (explain using orbital diagrams). e) Determine whether the complexes will be attracted to or repelled by an applied magnetic field. f) Lastly, report whether each complex is a high or a low spin complex.

9 24. Consider the following reduction half-reactions operating under standard conditions in a working galvanic cell: MnO 4 - (aq) + 8H + (aq) + 5 e- ! Mn 2+ (aq) + 4H 2 O(l) Pb 2+ (aq)+ 2e- ! Pb(s) a) Write the anode half-reaction, the cathode half-reaction, and the net equation for this electrochemical cell. b) Calculate E° for the cell. c) Give the cell in line notation. d) Calculate Keq and Gº in kJ for this reaction (for one of these, your calc should read overflow… hint, hint). e) Sketch a diagram of the galvanic cell. Make sure to include: the direction of e- flow, the voltmeter (label + or -), the correct placement of the chemical species involved in the reaction and their concentrations, identify the anode and cathode and designate their sign (+/-).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
