How many salt complexes would result if you treated racemic phenethylamine with racemic tartaric acid? After treating them with NaOH and extracting, would your extraction have been sucessful? Briefly explain why or why not
Estimate and plot the vapor pressure (atm) of neat methacrylate, dioctyl phthalate and 2,3,7,8-octachlorodibenzodioxin over the temperature range 0oC-25oC.
Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)

Construct a plot of the Gibbs free energy of this system as a function of partial pressures of BrCl as the reaction approaches equilibrium.
What is the value of Delta G when [H+]= 1.6×10?8 ,[CH3NH3] = 5.0×10?4 , and [CH3NH2] = 0.110 delta Go=19.1
Calculate the pH of the solution after the addition of 30ml of 0.1M NaOH. Draw the structure of the form is His predominating in solution at neutral pH.
Devise a suitable reaction sequence in which each of the following compounds can be prepared from benzene in good yield. Assume ortho and para isomers are separate from one another, and use any other reagents you desire.
what is the maximum mass of sucralose (C12H19Cl3O8) you can add to 3.0 kg of pure water and still have the solution freeze? Assume that sucralose is a molecular solid and does not ionize when it dissolves in water
Sickle-cell anemia is caused by a genetic defect that substitutes valine for glutamic acid at one position in two of the four chains of the hemoglobin protein. The result is a decrease in the water solubility of hemoglobin.
