10. 2Au(s) + 3Ca²(aq) → 2Au" (aq) + 3Ca(s) A. Write the line diagram for this cell. (6 pts) 11. (19 pts) tis Eºcell? B. Using standard reduction potentials included in your exam(see last page), what is t What is your understanding of this value? (4 pts) C. How can you improve the working of this cell? (3 pts) D. Using the data from your answer in C above, calculate the free energy(AG) of the reaction when [Au³"] = 0.1 M and [Ca³"]= 0.01 M (6 pts) When a solution of an unknown metal salt is electrolyzed with a current of 1.0 A for a time of 2.0 h, 0.025 mol of the metal forms (MM of M 157.25 g/mol). Calculate the charge on the unknown metal ion in the salt. (10 pts)
