Answer:- 
Solution:- percent ionization = 
where, 
is the equilibrium concentration of product ion and c is the initial concentration of the acid.
Let's plug in the values in the formula:
In general, the acid is represented as HA, the ice table is shown as:
I 0.10 0 0
C -X +X +X
E (0.10 - X) X X
where X is the change in concentration that we already have find out using percentage ionization formula.
![Ka=\frac{[H^+][A^-]}{[HA]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BA%5E-%5D%7D%7B%5BHA%5D%7D)
Let's plug in the values in it:
0.003 is almost negligible as compared to 0.10, so (0.10 - 0.003) could be taken as 0.10.
Second choice is the right one.

Answer: Molarity of the solution is 
and water is the solvent.
Explanation:
Given: Mass of solute = 26.8 g
Volume = 4.00 L
Now, moles of copper (II) chloride (molar mass = 134.45 g/mol) are calculated as follows.
Molarity is the number of moles of a substance divided by volume of solution in liter.
Therefore, molarity of given solution is calculated as follows.
Solvent is defined as a component which is present in higher amount in a solution. Generally, a solvent is present in liquid state but it can also be a solid or gas.
In the given solution, copper (II) chloride is dissolved in water so copper (II) chloride is the solute and water is the solvent.
Thus, we can conclude that molarity of the solution is and water is the solvent.
I would think radon would be the most reactive.
