Interpretation: The galvanic cell for the given reaction with the details of metal ions oxidized and reduced, half-cell reaction on each metal electrode needs to be determined.
Concept Introduction:In the
The reaction at each electrode is called as half-reaction and combination of both half-reaction gives the cell reaction of given electrochemical cell.

Answer to Problem 32A
Half-Reaction:
Explanation of Solution
Given information:
In the given reaction, solid zinc involves in oxidation at anode whereas lead ions reduce at cathode.
The positive electrode is anode and negative electrode is cathode. Thus, half-reactions must be:
- Oxidation = at anode
- Reduction = at cathode

- b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
