1. If the solubility of a gas is 6.5 g/L at 808 kPa pressure, what is the solubility of the gas when the pressure is 404 kPa? Show your work. 2. Explain on a particle basis how the addition of a solute affects the boiling point, the freezing point, and the vapor pressure of the solvent. 3. Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH–] is 1 x 10–9 mol/L. Is this solution acidic, basic, or neutral? Show your work. 4. What are 2 factors that determine how much solute will dissolve in a given solvent? 5. What are 3 factors that affect how fast a solute will dissolve in a solvent? 6. Calculate the acid dissociation constant of a weak monoprotic acid if a 0.4 M solution of this acid gives a hydrogen-ion concentration of 0.000 1M? Hint: Monoprotic means containing one proton. Show your work. 7. Give 3 properties of acids and 3 properties of bases.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
