31. An electrochemical cell is constructed with a zinc metal anode in contact with a 0.052 M solution of zinc(II) nitrate and a silver cathode in contact with a 0.0042 M solution of silver(I) nitrate. What is the cell potential of this electrochemical cell at 5°C? Metal/Metal ion rel silver/silver(I) zinc/zinc(II) +0.799 V -0.762 V 1.656 V b. 1.465 V c. 1.561 V d. 1.370 V 1.609 V а. е.

Consider the four hypothetical metals W, X, Y, and Z. The following observations were made when Y and W were inserted into X(NO3)2 and Z(NO3)2 solutions. W(s) + X² + (aq) →→X(s) + W²+ (aq) Y(s) + Z²+ (aq) → Z(s) + Y²+ (aq) Y(s) + X²+ (aq) → no reaction W(s) + Z²+ (aq) → Z(s) + W²+ (aq) The best reducing agent is:
