Consider two cells, the first with Al and Ag electrodes, and the second with Zn and Ni electrodes, each in appropriate 1.00M solutions of their ions.
a) if connected as a voltaic cells in series, which two metals are plated, and what is the total potential?
b) If connected such that one cell acts as a battery to power the other as an electrolytic cell, which two metals are plated and what is the total potential?
c) If 4.00g of metal is plated in the voltaic cell, how much metal is plated in the electrolytic cell?
Calculate the binding energy per nucleon (in MeV) for P-32 (atomic mass = 31.9739 u). mass H = 1.007825 u and mass n = 1.008665 u.
Several artificial nitrogenous bases, called base analogues, can be taken up by cells, converted to nucleotides, and incorporated into nucleic acids. They are often potent mutagens, and some are used in cancer chemotherapy.
