(a)

Interpretation Introduction

To determine: The structure of cholic acid that shows the rings in their chair conformations, and each methyl group and hydroxyl group as axial and equatorial.

Interpretation: The structure of cholic acid that shows the rings in their chair conformations, and each methyl group and hydroxyl group as axial and equatorial is to be stated.

Concept introduction: Cholic acid is also known as natural or primary bile acid that is insoluble in water but soluble in acetic acid and alcohol.

(b)

Interpretation Introduction

To determine: The structure of the cholic acid-glycine combination and an explanation corresponding to the given statement that cholic acid-glycine is a good emulsifying agent.

Interpretation: The structure of the cholic acid-glycine combination and an explanation corresponding to the given statement that cholic acid-glycine is a good emulsifying agent is to be stated.

Concept introduction: The nature of cholic acid-glycine combination is similar to the nature of soap and detergent. The cholic acid-glycine has highly polar head and slightly polar tail.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NO2 (g) = N2O4(g) AGº = -5.4 kJ Now suppose a reaction vessel is filled with 4.53 atm of dinitrogen tetroxide (N2O4) at 279. °C. Answer the following questions about this system: Under these conditions, will the pressure of N2O4 tend to rise or fall? Is it possible to reverse this tendency by adding NO2? In other words, if you said the pressure of N2O4 will tend to rise, can that be changed to a tendency to fall by adding NO2? Similarly, if you said the pressure of N2O4 will tend to fall, can that be changed to a tendency to '2' rise by adding NO2? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO 2 needed to reverse it. Round your answer to 2 significant digits. 00 rise ☐ x10 fall yes no ☐ atm G Ar 1
