How will aqueous solutions of sucrose and hydrogen chloride differ?

Interpretation:
The difference between the aqueous solutions of sucrose and hydrogen chloride needs to be explained.
Concept introduction: Sucrose is a disaccharide molecule with molecular formula
Hydrogen chloride has the formula HCl. HCl is a colorless gas at room temperature.
Answer to Problem 104A
In Aqueous solution, Sucrose does not dissociate but HCl molecules dissociates.
Explanation of Solution
Hydrogen chloride is a molecular compound with polar covalent bonds while sucrose is a carbohydrate with non-polar covalent bonds. Sucrose doesn’t dissociate into ions when dissolved in water. Hydrogen chloride molecules dissociate into hydrogen ions and chloride ions when dissolved in water to form an aqueous solution.
Thus, in Aqueous solution, Sucrose does not dissociate but HCl molecules dissociates.

- 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.
