- How does hydraulic fracturing differ from previously used techniques for the recovery of natural gas from the earth?2.) It’s a bad day in the lab! Two students are doing experiments. Each is 20 feet away from the professor. At the same time, each of them lets the same amount of a smelly gas into the room. One of them releases ammonia, NH3, and the other releases SO2. NH3 has a pungent odor, and SO2 smells like rotten eggs. The professor has no idea that this has happened, until she smell the first gas. Which chemical will the professor smell first? (NH3 or SO2) . If the professor starts to smell the first gas 42. seconds after the gas is released, how long will it take her to smell the second gas? sec. * Note: It is unsafe practice to work with these chemicals in an open lab.(a) What is the difference between chlorofluorocarbonsand hydrofluorocarbons? (b) Why are hydrofluorocarbonspotentially less harmful to the ozone layer than CFCs?
- Some pollutants are difficult to break down and therefore accumulate in the environment. These are termed chronic pollutants. non-persistent pollutants. persistent pollutants. chemical indicators.Chemistry and Environmental Pollution Using suitable examples, discuss the chemical, biological, and physicalreactivity processes of contaminants.5.00 mol of ammonia are introduced into a 5.00 L reactor vessel in which it partially dissociates at high temperatures.2NH3(g) 3H2(g) + N2(g)At equilibrium and a particular temperature, 1.00 mole of ammonia remains. Calculate Kc for the reaction. Hint - divide 5.00 mol of ammonia by 5.00 L to get initial concentration. Round off the answer to three significant digits. Group of answer choices Kc = 15.3 Kc = 17.3 Kc = 19.3 Kc = 21.3 None of the above

- 16. The combustion of gasoline (octane) in a car engine can be represented by the following equation: 2C3H18(1) + 2502(g) a. What mass of oxygen is used up to burn a full tank of 36.00 kg of gasoline? Text --> 16CO2(g) +18H20(g) b. Why might a vehicle that is calibrated to run perfectly at sea level run poorly at higher elevations? Text Тext According to the Canadian Automobile Association, the average Canadian drives 20,000 km/yr. C. Assuming that distance, how many more kg of carbon dioxide are added to the atmosphere each year by a Toyota Tacoma (fuel economy of 12.8 L/100 km) than a Toyota Prius (4.52 L/100 km)? The density of gasoline is 0.719 kg/L.What is the method of analysis for the chemical pollutants of soil pollution?A commercial 737 jet transporting 143 passengers and 5 crew members from Kansas city (MCI) to Baltimore (BWI) burned 11800 lb. of Jet A fuel. Jet A fuel is kerosene 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 would be released into the atmosphere if those passengers and crew made the trip instead, in pairs, in hybrid cars at 50 miles per gallon. (Assume the density of gasoline to be 0.75kg L-1 and that carbon and hydrogen dominate the composition in a ratio 1:2. The road trip is 1082 miles.
