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)?

21. ADLC Assignment Booklet A3 Decide whether each statement is true (T) or false (F). Place your answer in the blank space given. Scientific theory states that the atoms in today's plastics were parts of microscopic plants and animals that lived in the oceans millions of years ago. b. Molecules of gasoline have more carbon atoms than do molecules of diesel fuel. c. Subjecting large molecules to cracking is useful because smaller molecules are manipulated more easily in a reaction to produce a desired product. d. Unsaturated compounds form during hydrocarbon cracking because too many hydrogen atoms are available for the number of carbon atoms.
