Benzene has acute health effects. For example, it causes mucous membrane irritation at a concentration of 100 ppm and fatal narcosis at 20,000 ppm (by volume). Calculate the partial pressures in atmospheres at STP corresponding to these concentrations.
As weather balloons rise from the earths surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperatura is much lower in the upper atmosphere than at sea level. Would this temperatura effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you?
Oxygen Consumption If 5.00 L of hydrogen gas,measured at a temperature of 20.0°C and a pressure of80.1 kPa, is burned in excess oxygen to form water, whatmass of oxygen will be consumed? Assume temperatureand pressure remain constant.
At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. A 0.8765-g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen gas collected over water occupied 57.2 mL at a temperature of 22C and a pressure of 734 torr. Calculate the mass percent of NaClO3 in the original sample. (At 22C the vapor pressure of water is 19.8 torr.)
What volume of O2 at STP is required to oxidize 8.0 L of NO at SW to NO2? What volume of NO2 is produced at SW?
A ballon used for sampling stratospheric ozone is filled with 150.0 kg of He. What is the volume of the balloon when,a. The balloon starts from a research station in Antartica at sea level where the barrometric pressure is 755 mmHg and thetemperature is -25.0 °C.b. The balloon rises to 29,028 ft (8,848 m, the height of Mt Everest and about typical crusing altitude for a jet aircraft) thetemperature is -70 °C and the pressure is 2.30x104 Pa.c. The balloon enters the stratosphere, at 65000 ft (20,000 m, crusing altutude for a U2 spy plane) the temperature is -70 °Cand the pressure is 3.68x103 Pa.
Global warming’s drastic effect were attributed to the rapid accumulation of “greenhouse gases”in the atmosphere. Naming carbon dioxide as its major contributor, is formed when fossil fuels arecombusted in different power plants (e.g. fuel powered, namely by coal, oil, or natural gas). Some of thepotential way to reduce the amount of carbon dioxide that is added to atmosphere is to compress the gasin underground formations. We can consider this with a 1000-MW coal-fired power plant that produces an amount of 6.0 × 10^6tons of CO2 per year. (a) In an ideal gas – or perfect gas behavior, 1.00 atm, 27°C, calculate the volume of the carbon dioxide produced by the power plant mentioned. (b) What volumecan we obtain if CO2 (liquid form) stored in underground has an equation of state as 10 °C, 120 atm, anddensity of 1.2 g/cm^3? (c) Storing this underground as gas [on another note] at 36 °C and 90 atm, whatvolume can it occupy? Is the volume is larger or smaller than in liquid form? Explain.
The world burns approximately 3.7 * 1012 kg of fossil fuel per year. Use the combustion of octane as the representative reaction and determine the mass of carbon dioxide (the most significant greenhouse gas) formed per year. The current concentration of carbon dioxide in the atmosphere is approximately 399 ppm (by volume). By what percentage does the concentration increase each year due to fossil fuel combustion? Approximate the average properties of the entire atmosphere by assuming that the atmosphere extends from sea level to 15 km and that it has an average pressure of 381 torr and average temperature of 275 K. Assume Earth is a perfect sphere with a radius of 6371 km.
A prevailing pressure of one standard atmosphere will support a column of mercury 760 mm in height. Liquid carbon tetrachloride has a density of 1.59 g/mL. The height of a column of carbon tetrachloride that one standard atmosphere can support is ? mm.
The density of moist air (ideal gas mixture) at 20°C temperature and 700 mmHg pressure was found to be 1.1 g/lt. Calculate the partial pressure of water vapor in this air. Additional data: MA(H2O)18, MA (Air)29
The figure shows the three lowest regions of Earth’s atmosphere.(a) Name each and indicate the approximate elevationsat which the boundaries occur. (b) In which region isozone a pollutant? In which region does it filter UV solarradiation? (c) In which region is infrared radiation fromEarth’s surface most strongly reflected back? (d) An auroraborealis is due to excitation of atoms and molecules inthe atmosphere 55–95 km above Earth’s surface. Whichregions in the figure are involved in an aurora borealis?(e) Compare the changes in relative concentrations ofwater vapor and carbon dioxide with increasing elevationin these three regions
