Answer :
In my opinion , answer is A
<u>Answer:</u> The molar solubility of MX is 
<u>Explanation:</u>
We are given:

The chemical equation for the ionization of MX follows:

S S
The expression of
for above equation is:
......(1)
The chemical equation for the ionization of
follows:

0.25M 0.5M 0.25M
Total concentration of cation from both the equation is:
![[M^+]=0.5+S](https://tex.z-dn.net/?f=%5BM%5E%2B%5D%3D0.5%2BS)
As,
, so S is also very very less than 1 and can be easily neglected.
So, ![[M^+]=0.5M](https://tex.z-dn.net/?f=%5BM%5E%2B%5D%3D0.5M)
Putting values in equation 1, we get:

Hence, the molar solubility of MX is 
False the output force and input force is low because the formula is output force divided by input force. Just a note you are not doing much input force into the screw because you hold the screwdriver
This is a physical change.
