8. Down in the engineering lab, they are trying to make a galvanic (voltaic) cell. Given that they are using the two half reactions below at standard conditions to make the cell, what species are produced at each electrode? What would the potential be for the cell? E' (volts) 0.80 Ag (aq) + e - Ag(s) NP+ (aq) + 2 e-Ni (s) - 0.23 9. The age of any remains from a once-living organism can be determined by radiocarbon dating, a procedure that works by determining the concentration of radioactive "C in the remains. All living organisms contain an equilibrium concentration of radioactive C that gives rise to an average of 15.3 mg of carbon. (These nuclear decay events are used as concentrations for any calculations.) At death, however, no additional C is taken in, so the concentration slowly drops as radioactive decay occurs. A bone fragment has been found on the planet's surface and shows an average of 2.3 mg of carbon. If the half-life for the radioactive decay of C is 5715 years how old is the bone fragment? 10. For your final assignment aboard the Starship Enterprise you are asked to help an ensign in the physical science division. The Kap for silver chloride at 25°C is 1.782 x 10-10. At 35 °C, Kop is 4.159 X 10 -10. What are the values of AH and AS for the reaction? (Hint: it is a 2 equation with 2 unknown problem).
