There are a lot of separation processes. To name a few, these can be distillation, centrifugation, extraction, membrane or sorption process and many other. To know which is the best technique, you should know the property between two substances that have a stark difference. In this case, it is the polarity. Ethyl alcohol is more polar than ethyl ester and less dense. Thus, these two won't mix. So, take advantage of their density difference by decantation or centrifugation.

Answer: <em>
pH=2.25 </em></h3>
Explanation:
monochloroacetic acid also means: chloroacetic acid
pKa of monochloroacetic acid= 1.4 x 10^-3 (I believe this should have been given in the problem or perhaps in the textbook)
Formula: pH= pKa + log ( some number in M)
pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25
pH= 2.25
Answer:
A.
Explanation:
We know quite well that there are three states of matter. Solid,liquid and gaseous states.
While the gaseous states gives the highest freedom of movement, the solid state gives the least freedom of movement. Molecules and atoms of a solid are so tightly packed.
This makes them very dense as they are held together by strong intermolecular forces of attraction. These strong forces prevents the movement of the particles.
As these particles are strongly attracted towards each other, they tend to be incompressible.
