Name Page 2 of 11 Part I: Multiple Choice, Concepts (4 points each) Select the best answer and enter your choice on the cover sheet - No partial credit 1) A galvanic cell uses the reaction described by the following chemical equation: Zn(s) + Ni 2 +(aq) ~ Zn2+(aq) + Ni(s) EO = + 0.50 V Which of the following statements about this cell is TRUE? a) The nickel electrode is negatively charged. b) The cell notation is: Ni I Ni2+ II Zn2+ I Zn c) The zinc electrode is the anode. d) EO > 0 for the cell means that starting with [Ni2+] = [Zn2+] = 1 M, when the cell is dead, it will be [Ni2+] > [Zn2+]. e) None of the above. @AT2009FALL 2) 3) Consider the coordination compounds, [MXY5]A and [MAY 5 ]X with M = metal atom, Y = ligand, A = ligand or counter ion and X = ligand or counter ion. These two compounds exhibit: a) Geometric isomerism b) 0 tical isomerism c) Ionization isomerism d) Coordination isomerism e) Linkage isomerism @AT2009FALL Suppose you have a battery functioning as a galvanic cell at standard state conditions.
