The pressure exerted by a column of liquid is equal to the product of the height of the column times the gravitational constant times the density of the liquid, P= ghd. How high a column of methanol (d = 0.79 g/mL) would be supported by a pressure that supports a 713 mm column of mercury (d = 13.6 g/mL)? 1.2 x 104 mm B 41 mm 713 mm 9.7 x 103 mm E 17 mm

In the Mthode Champenoise, grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is C6H12O6(aq)2C2H5OH(aq)+2CO2(g) Fermentation of 750. mL grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 825 mL until 12% by volume is ethanol (C2H5OH). Assuming that the CO2 is insoluble in H2O (actually, a wrong assumption), what would be the pressure of CO2 inside the wine bottle at 25C? (The density of ethanol is 0.79 g/cm3.)
Silicon nitride, Si3N4, is a material that is used in computer chips as an insulator. Silicon nitride can be prepared according to the chemical equation 3SiH4(g)+4NH3(g)Si3N4(g)+12H2(g) If you wanted to prepare a surface film of Si3N4(s) that had an area of 9.0 mm2 and was 4.0 105 mm thick, what volume of SiH4 gas would you need to use at 1.0 105 torr and 775 K? The density of Si3N2 is 3.29 g/cm3.
A McLeod gauge measures low gas pressures by compressing a known volume of the gas at constant temperature. If 315 cm3 of gas is compressed to a volume of 0.0457 cm3 under a pressure of 2.51 kPa, what was the original gas pressure?
Answer the following questions: (a) If XX behaved as an ideal gas, what would its graph of Z vs. P look like? (b) For most of this chapter, we performed calculations treating gases as ideal. Was this justified? (c) What is the effect of the volume of gas molecules on Z? Under what conditions is this effect small? When is it large? Explain using an appropriate diagram. (d) What is the effect of intermolecular attractions on the value of Z? Under what conditions is this effect small? When is it large? Explain using an appropriate diagram. (e) In general, under what temperature conditions would you expect Z to have the largest deviations from the Z for an ideal gas?
