Document Summary

Ethanol (c2h5oh) has a normal boiling point of 78. 3oc and hvap=39. 3 kj/mol. Note that 1 atm = 760 torr: 234 torr, 670 torr, 118 torr. D)354 torr e)485 torr: a substance has a heat of fusion of 61. 5 kj/mol and a heat of deposition of -167. 4 kj/mol. What is the heat of sublimation in kj/mol? a) D)167. 4: 105. 9, arrange the following compounds in order of increasing boiling point: i 1-propanol, (structure ch3ch2ch2oh); ii 1,2-propanediol, (ch3ch(oh)ch2oh); iii 1,2,3- propanetriol, (glycerol, with structure hoch2ch(oh)ch2oh) a) In a particular unit cell, all sides areequal in length and all angles are right angles. There is an atom at each corner and one at the center of each side. What is the composition of the vapor in equilibrium with a propyl alcohol isopropyl alcohol solution at 25oc in which the mole raction of propyl alcohol, xprop, is. 0. 250: xiso=0. 317, xpop= 0. 683, xiso = 0. 512, xpop= 0. 488, xiso = 0. 750, xprop= 0. 250.
