The answer would be E, it shows students how the different environments appear, since you can visually see it.
The answer is the most probable location of electrons in an atom
<u>Answer:</u> The value of <em>i</em> is 1.4 and 40% dissociation of 100 particles of zinc sulfate will yield 60 undissociated particles.
<u>Explanation:</u>
The equation used to calculate the Vant' Hoff factor in dissociation follows:

where,
= degree of dissociation = 40% = 0.40
i = Vant' Hoff factor
n = number of ions dissociated = 2
Putting values in above equation, we get:

The equation used to calculate the degee of dissociation follows:

Total number of particles taken = 100
Degree of dissociation = 40% = 0.40
Putting values in above equation, we get:

This means that 40 particles are dissociated and 60 particles remain undissociated in the solution.
Hence, 40% dissociation of 100 particles of zinc sulfate will yield 60 undissociated particles.
