Solution : Water and Methanol are easily miscible in any amount. so they are not preferred for the liquid-liquid extraction process.
Liquid-Liquid Extraction is also called as solvent extraction. It is the method of seperation of compound based on their relative solubilities in two different immiscible liquids. Generally we use water (polar) and an organic solvent (non-polar).
It is important that the two solvents should not be mix because it is easy to seperate them.
Water and Methanol are easily miscible in any amount. we can not seperate them easily. So that is why we can not use water and methanol as a solvent in liquid-liquid extraction process.

i have taken environmental science so i can help
Answer:
amine
Explanation:
We have to bear in mind that amines are basic compounds. This idea will be very important in attempting to answer this question.
So, when she adds 5% HCl solution in order to extract the organic layer, the amine forms a hydrochloride salt which is contained in the aqueous layer.
The addition of a base such as NaOH leads to the formation of a white precipitate of the amine.

Answer:
760.39 mmHg (approx.)
Explanation:
Okay so given the first set of information, we have:
T = 406 K (133+273)
V = 20 L
P = 1.1184 atm (converted for continuity reasons from mmHg)
R = 0.08206 L atm/mol K
Using PV = nRT (ideal gas law), we solve for n (moles of SO2).
n = PV/RT = (1.1184 atm * 20 L) / (0.08206 L atm/mol K * 406 K) = 0.6714 mol
Now that you have all the information, you can use the new volume and temperature to solve for pressure.
T = 454 K (181+273)
V = 25 L
n = 0.6714 mol
R = 0.08206 L atm/mol K
Using the ideal gas law again, we solve for P (pressure in <u>atm</u>).
P = nRT/V = (0.6714 mol * 0.08206 L atm/mol K * 454 K) / (25 L) = 1.0005 atm
Then we convert atm back to mmHg to get 760.39 mmHg.
