Answer:
D
Explanation:
Double the first equation. Write the second below it. Rearrange the second.
2x - 20 = - 4y
<u>-2x -16= +4y</u> Add.
- 36 = 0
There is no solution to this pair of equations.
Answer:
The lattice energies for the alkali metal halides is therefore largest for LiF and smallest for CsI, as shown in the table below. The ionic bond should also become stronger as the charge on the ions becomes larger.

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.
