32. (Bonus) Americans combined drive about 4.0 x 109 kilometers a day and get an average of 20 miles per gallon of gasoline. For each kilogram of gasoline that is burned about 3 kg of carbon dioxide (CO2) are produced. With the density of gasoline as 0.93 g/cm3, how many kg of CO2 are emitted by U.S.cars into the atmosphere each minute? (1 gallon 3.7854 L, 1 mile 1.609 km) 4.7 x 109 kg CO2/min 5.47 x 107 kg CO2/min...

3. If 18.5 gallons of gasoline are burned while driving to the mountains, how many pounds of carbon dioxide are produced? You will need to write a complete balanced equation, including phase labels, for this combustion reaction (gasoline can be approximated by C8H18 and has a density of 0.72 g/cm'). You will also need to use the following equivalence statements: 1 lb = 0.071429 stone, 6.35 kg - 1 stone, 1 gallon = 1024 fluid drams (fl dm), 1 fluid...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
