3. A standard copper-zinc cell is constructed based on the following reaction. 2Cu(s) + Zn(NO3)2(aq) → 2CUNO3(aq) + Zn(s) Which of the following is the correct setup for determining the cell potential of this cell? See Table 2 in Appendix A for the standard electrode potential values. a. AE° =-0.52 V – - (+0.76 V) =-1.28 V b. AE° =-0.52 V – (-0.76 V) =+0.24 V c. Both (a) and (e) are correct d. AE° = +0.52 V – (+0.76 V) =-0.24 V e. AE° = +0.52 V – (-0.76 V) =+1.28 V f. None of these options are correct 4. Which of the following reaction types are always a redox reaction? Choose ALL correct answers. a. Combustion b. Decomposition c. Double Replacement d. Neutralization e. Single Replacement f. Synthesis
