"The forces of attraction and the volume of the molecules" (as opposed to the volume of the container the gas is in).
Answer:
You did very well and its correct.
Explanation:
Great Job!
Answer:
At least 3 three extractions are required to recover at least 99.5 % of the material in the organic layer.
Explanation:
The partition coefficient of a solute (S) soluble in two immiscible solvents is given by the following formula
The lower layer is taken as an aqueous layer (1), while the upper layer is organic (2). The fraction of solute remaining in the aqueous layer is given by the following formula
Here, n denotes the number of extraction, and q^n represents the fraction of solute remaining in aqueous solvent after n number of extraction. According to the given data, the fraction of solute remaining in the aqueous layer after multiple extractions is 0.005, i.e., q^n=0.005. Mathematically,
Taking log on both sides
The above calculations show that the number of extractions should be greater than 2, i.e, at least 3, in order to achieve extraction greater than 99.5 %.
Answer:
C. It decreases by a factor of 4
Explanation:
F1 = kq1*q2/r²
F2 = kq1*q2/(2r)² = kq1*q2/(4r²) = kq1*q2/(r²*4) = F1/4
