Item 44 of 16ae Review I Constants I Periodic TableGases are different from solids and liquids. In asample of gas, the molecules are far apart. The gasmolecules also move around and collide with eachother as well as with the walls of the container.These collisions generate pressure. The pressureof a gas can be measured in different units. Oneconvenient unit of measure is called theatmosphere (atm) because it is based onatmospheric pressure. At sea level, the averagepressure is 1 atm. As you get higher in altitude, thepressure steadily drops until you leave theatmosphere, where the pressure is very close to 0atm.Part CThe table below shows the different commonlyused units of measuring gas pressure. Use thistable in the pressure unit conversions.High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemicalsubstances. The pressures used in this procedure range from around 500 kilopascals (500,000 Pa) to about 60,000 kPa(60,000,000 Pa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of1.45x10° Pa , what is its running pressure in torr?1 atmExpress the pressure numerically in torr.UnitAbbreviationequivalent• View Available Hint(s)1.00 atmatmosphereatm(ехact)millimeters ofΑΣφ?mmHg760 mmHgmercurytorrtorr760 torr1.45x108 Pa =torrinches of mercuryin.

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.)
A sample of a compound of xenon and fluorine was confined in a bulb with a pressure of 18 tor. Hydrogen was added to the bulb until the pressure was 72 torr. Passage of an electric spark through the mixture produced Xe and HF. After the HF was removed by reaction with solid KOH, the final pressure of xenon and unreacted hydrogen in the bulb was 36 torr. What is the empirical formula of the xenon fluoride in the original sample? (Note: Xenon fluorides contain only one xenon atom per molecule.)

Most mixtures of hydrogen gas with oxygen gas are explosive. However, a mixture that contains less than 3.0 % O2 is not. If enough O2 is added to a cylinder of H2 at 33.2 atm to bring the total pressure to 3-13 atm, is the mixture explosive?
