What if you have a nonpolar substance such as hexane

Expert Solution

The attractive forces among the hexane molecules are the relatively weak London dispersion forces.

The attractive forces among the water molecules are the relatively strong H-bonds.

The only attractive forces among the hexane and water molecules are London forces.

Thus, a few hexane molecules will enter the water layer, but the strong attractive forces among the water molecules keeps most of the hexane molecules out.

Similarly, a few water molecules will enter the hexane layer because of the water-hexane London forces.

Water and hexane are immiscible. They do not dissolve in each other.

If we add hexane to water, the hexane will float on the top of the water with no apparent mixing.

You are given a substance that is equally soluble in water and hexane (two immiscible solvents). a.) If you start with 10 g of the substance dissolved in 100mL of water and are given 100mL of hexane to extract with how much will you extract into hexane if you do a single extraction with all 100mL of the hexane? b.) If you start with 10g of the substance dissolved in 100mL water and are given 100mL of hexane to extract...

1. Explain how an emulsifier can combine a nonpolar substance with a polar substance. 2. Mayonnaise is a thick mixture containing oil, vinegar (water-based), and a phospholipid molecule called lecithin found in the yolks of eggs. Mayonnaise cannot be made without lecithin. Explain why lecithin is a critical ingredient.?

Suppose you have been given the task of distilling a mixture of hexane + toluene. Pure hexane has a refractive index of 1.375 and pure toluene has a refactive index of 1.497. You collect a distillate sample which has a refractive index of 1.441. Assuming that the refractive index of the hexane + toluene mixture varies linearly with mole fraction, what is the mole fraction of hexane in your sample?

Suppose you have been diagnosed with an anxiety disorder or substance dependence and are trying to decide whether to enroll in individual therapy or group therapy. In 200-300 words, describe your decision-making process (i.e., how you weigh the pros and cons of both modalities), choose a course of action, and discuss why you chose that option

Researchers have described the “binary patterning” of polar and nonpolar amino acids in the sequences of proteins. In their code, polar and charged residues like D, N, E, Q, K, H, and R are represented as open circles (○) and nonpolar residues like F, L, I, M, and V as closed circles (●). Thus, a polypeptide with the sequence asp-ile-his-phe-gln would be represented as ○●○●○. Researchers analyzed the binary patterns of isolated secondary structure elements (short pieces) from native proteins....
