Explanation:
A substance that completely dissociates into ions when dissolved in its aqueous solution is known as a strong electrolyte.
Whereas a substance that does not dissociate into ions is known as a non-electrolyte.
If a substance partially dissociates into ions when dissolved in its aqueous solution then it is known as a weak electrolyte.
(a) ![A(l) \rightarrow A(aq)](https://tex.z-dn.net/?f=A%28l%29%20%5Crightarrow%20A%28aq%29)
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.
(b)
As partial dissociation of ions take place in this reaction as the reaction is in equilibrium state. Hence, it is a weak electrolyte.
(c) ![DE(aq) \rightarrow D^{+}(aq) + E^{-}(aq)](https://tex.z-dn.net/?f=DE%28aq%29%20%5Crightarrow%20D%5E%7B%2B%7D%28aq%29%20%2B%20E%5E%7B-%7D%28aq%29)
Here, complete dissociation of ions is taking place as the reaction is not in an equilibrium state. Therefore, it is a strong electrolyte.
(d) ![XY(s) \rightarrow X^{+}(aq)+Y^{-}(aq)](https://tex.z-dn.net/?f=XY%28s%29%20%5Crightarrow%20X%5E%7B%2B%7D%28aq%29%2BY%5E%7B-%7D%28aq%29)
Here also complete dissociation is taking place. Hence, it is a strong electrolyte.
(e) ![Z(s) \rightarrow Z(aq)](https://tex.z-dn.net/?f=Z%28s%29%20%5Crightarrow%20Z%28aq%29)
As there is occurring no dissociation. Hence, no formation of ions takes place therefore, it is a non-electrolyte.

Answer:
Weaker
Explanation:
Since the charges on nucleus and electron are opposite in nature, an attractive force exists between them. It is true in generally, that when objects are made to move closer together in the direction of an attractive force, potential energy decreases (and increases whenever attracting objects are force to move apart).
C. 25 Miles
This is because you have 12.5 moles of water and using the ratio this is 2 (molar ratio). Therefore the molar ratio for HF is 4, so 12.5 x 2 = 25 moles
