$SOLVED: If you were to attempt a simple distillation of a binary mixture composed of two liquids that have boiling points that are 51Â°C apart, what would be the result? How would this compare to a separation performed on a mixture of liquids that have a 112Â°C separation of boiling points? Explain your reasoning. Could the following miscible liquid pair be effectively separated by simple distillation or would it require fractional distillation? Explain your reasoning: n-Hexanol and Ethyl Acetat$

SOLVED:Trouton's rule states that for many liquids at their normal boiling points, the standard molar entropy of vaporization is about 88 J / mol-K (a) Estimate the normal boiling point of bromine, Br2, by determining ΔHvap^∘ for Br2 using data from Appendix C. Assume that ΔH vap ^∘ remains constant with temperature and that Trouton's rule holds. (b) Look up the normal boiling point of B r2 in a chemistry handbook or at the WebElements website (www..webelements.com) and compare it to your calcul

(Choose all that apply)Fractional distillation contains more theoretical platesFractional distillation possess more vaporization /condensation cyclesSimple distillation is an endothermic process and thus results in mixturesFractional distillation due to "physical barriers' filters out larger molecules only allow smaller ones to d

SOLVED:Suppose you have two colorless molecular liquids, one boiling at -84 ^∘ C, the other at 34 ^∘ C, and both at atmospheric pressure. Which of the following statements is correct? For those that are not correct, modify the statement so that it is correct. (a) The higher-boiling liquid has greater total intermolecular forces than the other. (b) The lower boiling liquid must consist of nonpolar molecules. (c) The lower-boiling liquid has a lower molecular weight than the higher-boiling liquid.

SOLVED:Consider two flasks that each contains different pure liquids at 20^∘ C. The liquid in one flask, substance A, has a molar mass of 100 g / mol and has hydrogen bonding. The liquid in the other flask, substance B, has a molar mass of 105 g / mol and has dipole-dipole interactions. a. If the molecular structures of the compounds are very similar, which flask likely contains substance A ? b. If you were to increase the temperature of each of the flasks by 15^∘ C, how would the pictures cha

SOLVED:Most liquids follow Trouton's rule (see Exercise 19.93), which states that the molar entropy of vaporization is approximately 88 ±5 J / mol-K . The normal boiling points and enthalpies of vaporization of several organic liquids are as follows: (a) Calculate ΔSvap for each of the liquids. Do all the liquids obey Trouton's rule? (b) With reference to intermolecular forces (Section 11.2), can you explain any exceptions to the rule? (c) Would you expect water to obey Trouton's rule? By usin
