Chlorodifluoromethane (CHF2Cl) was widely used in the compression/cooling circuits of refrigeration or air-conditioning systems. Since the discovery that such compounds (HCFCs and CFC's) released into the atmosphere were a major cause of depletion of stratospheric ozone, newer refrigeration systems make use of certain hydrofluorocarbons (HFCs), which are degraded in the lower atmosphere, instead. Often, mixtures of such compounds are used. Suppose a sample of refrigerant gas consisting of a simple mixture of the gases pentafluoroethane (C2HF5) and difluorormethane (CH2F2) has a density of 1.43 g/L at 26 °C and 0.405 atm. Calculate the average molecular mass for this sample. Calculate the volume percentage of CH2F2 in the sample.

100 millimoles of Ethane, C2H6 underwent compkete combustion in a furnace. If dry air used in the combustionbof ethane has no excess what would be the complete analysis of the flue gas?. It is hypotgesized that the flue gas contains N2, CO2, H2O and free O2.
(a) A commercial 737 jet transporting 143 passengers and 5 crew members from Kansas City (MCI) to Baltimore (BWI) burned 11,800 lb (about 1700 gallons) of Jet A fuel en route. Jet A fuel is kerosine based, consisting primarily of CnH2n+2 hydrocarbons, with n =6 to 16, so the carbon:hydrogen ratio is close to 1:2. During this flight, how much CO2 was released into the atmosphere? Assume the combustion of the fuel was complete, so all the fuel was burned to form CO2 and H2O. Give both the mass of CO2 produced (in kg and in lbs) and the volume it would occupy at 298 K, 1 atm.(b) How much CO2 would be released into the atmosphere if those passengers and crew made the trip instead, in pairs, in hybrid cars at 40 miles per gallon. Assume the density of the gasoline is 0.75 kg L-1 and that carbon and hydrogen dominate the composition in a ratio of 1:2. The road trip is 1082 miles.
A water contains 50.40 mg · L−1 as CaCO3 of carbon dioxide, 190.00 mg · L−1 as CaCO3 of Ca2+ and 55.00 mg · L−1 as CaCO3 of Mg2+. All of the hardness is carbonate hardness. Using the stoichiometry of the lime soda ash softening equations, what is the daily sludge production (in dry weight, kg · day−1) if the plant treats water at a rate of 2.935 m3 · s−1? Assume that the effluent water contains no carbon dioxide, 30.0 mg · L−1 as CaCO3 of Ca2+ and 10.0 mg · L−1 as CaCO3 of Mg2+. Be sure to calculate the mass of CaCO3 and Mg(OH)2 sludge produced each day.
In the synthesis of hydrocarbons, the carbon source is carbon dioxide. Although the CO2 concentra?on in the atmosphere raises at a drama?c speed, point sources are probably the easier sources for a PtX process. Iden?fy 3 possible point sources, explain why CO2 is formed and what challenges each of the three CO2 streams presents
Combustible vapor-air mixtures are flammable over a limitedrange of concentrations. The minimum volume % of vapor thatgives a combustible mixture is called the lower flammable limit(LFL). Generally, the LFL is about half the stoichiometric mix-ture, the concentration required for complete combustion of thevapor in air. (a) If oxygen is 20.9 vol % of air, estimate the LFL forn-hexane, C₆H₁₄. (b) What volume (in mL) of n-hexane (d=0.660 g/cm³) is required to produce a flammable mixture of hexane in 1.000 m³of air at STP?
Freon-12 (CF₂Cl₂), widely used as a refrigerant and aerosolpropellant, is a dangerous air pollutant. In the troposphere, ittraps heat 25 times as effectively as CO₂, and in the stratosphere,it participates in the breakdown of ozone. Freon-12 is preparedindustrially by reaction of gaseous carbon tetrachloride with hy-drogen fluoride. Hydrogen chloride gas also forms. How manygrams of carbon tetrachloride are required for the production of16.0 dm₃ of Freon-12 at 27°C and 1.20 atm?
Acetylene had many uses at the time of the First World War, because it burned with a hot and luminous flame mainly. The oxyacetylene apple and the period of the oxyacetylene car company and bicycles made this good represent well. In an attempt to find a route to acetylene other than through calcium carbide, a Prest-O-Lite sponsored research by George O. Curme of the Mellon Institute in Pittsburgh. Ethylene research was directed towards converting gases for refining petroleum methods, led to more polyethylene material for acetylene production. Viewed from today's perspective, the Curme route to petroleum-based ethylene ranks as an important discovery. However, this was not the case at the time, because ethylene had almost no use before 1920. Curme's second major contribution was the research he carried out to see what useful products he could make with ethylene. The first was ethylene glycol, which became Prestone antifreeze. Others follow and now ethylene is evidently the most…
