A voltaic cell is constructed by immersing a strip of silver metal in a 1.0M AgNO3 solution and a strip of Cadmium metal in a 1.0M Cd(NO)3 solutio. the circuit is completed by a wire and a salt bridge in the usual way. Answer questions a-e:
a. Balanced overal cell reaction
b. What is the cell potential for the voltaic cell
c. Write the balanced half-reaction that is ocurring at the anode
d. Write the balanced half-reaction ocurring at the cathode
e. What would the potential of the cell if it was modified to use 0.10M AgNO3 solution and a 0.30M Cd(NO)3 solution instead?
Calculate the wavelength, in nanometers, of the spectral line produced when an electron in a hydrogen atom undergoes the transition from the energy level n = 7 to the level n = 2.
