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...
