The major difference is that the operating potential of the lithium-iodine cell indicates its' cell reaction is more thermodynamically favorable.
<h3>What is the difference in cell potential?</h3>
The Zinc-Mercury Cell reaction is; Zn + HgO = ZnO + Hg. It also has long storage life and stable voltage(1.35V).
The major difference between the zinc-mercury cell and the lithium-iodine cell is that during the initial cell operation, each reaction is thermodynamically favorable, but the larger operating potential of the lithium-iodine cell indicates that its cell reaction is more thermodynamically favorable.

The final temperature on the block is 25 degrees.
Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.
Data given;
- M1 = 3.33g
- T1 = 25 degrees
- M2 = 44g
- T2 = 25 degree
- C1 = 124.5 J mol K
- C2 = 0.89 J/g K
<h3>Heat Transfer</h3>
Applying the principles of heat transfer,
Heat loss = Heat gain
From the calculation above, the final temperature on the block is 25 degrees.
