Determine if each of the following is a solution, colloidal dispersion, or suspension. Why? a. A white, cloudy liquid is left overnight and separates into two layers. b. A clear, colorless liquid is left in an open container. The liquid evaporates leving a white residue. c. A write, cloudy liquid is run through a filter. The filtrate is a white, doudy liquid. Video 2 Why is the molality of a solution always greater than its molerier? Would the difference be greater with a liquid solute in a liquid selvent or a solid solve in liquid solvent? Why? How does the mole fraction of a solute compure to the mole fraction of its solvent?Video 3 Determine if each salt is soluble or insoluble in water. a.
MgCl_(2)
d.
LNO_(2)
b.
CaSO_(4)
e. WhabSO c. Adf i.
(S)/(OH)/2
How does the solubility of gases change with increased temperature? What else changes the solubility of gases? Video 4 How does the vapor pressure of a liquid change as the semperature of the liquid increases? Why? How does the istrength of intermolecular attractions affect the vapor pressure of the liquid? Why? Which liquid would you expect to have the greatest vapor pressure? Lowest vacor pressure? Why? a.
CH_(4)
b. HF c.
CH_(3)Cl
How does the vapor pressure of a solvent change when a nonolatile salue is added? Why?How does the boiling point of water in a pressure cooker compare to the boiling point of water in an open pot? Explain. Videos 5 Video 1 Determine the solute and the solvent in each of the following solutions. a.
