6.4. The vapor pressure of ethylene glycol at several temperatures is given below:

T (C) 79.7 105.8 120.0 141.8 178.5 197.3

p* (mmHg) 5.0 20.0 40.0 100.0 400.0 760.0

Use a semilog plot based on the Clausius-Clapeyron equation to derive an equation for p* (mm Hg) as a function of T (C). From the plot, estimate the heat of vaporization of ethylene glycol in kJ/mol.

Clausius-Clapeyron equation: ln p* = -Hv/RT + B

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.

0.2348 grams of pbcl2 used to form 44.0 ml of solution.

Magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. trial 1: trial 2: data mass of empty crucible with lid trial 1: 26.688 trial 2: 26.681 mass of mg metal, crucible, and lid trial 1: 26.994 trial: 2 26.985 mass of mgo, crucible, and lid trial 1: 27.188 trial 2: 27.180
