1. Calculate the number of pounds of CO2 released into the atmosphere when a 15.0-gallon tank of gasoline is burned in an automobile engine. Assume that gasoline is primarily octane, C8H18, and that the density of gasoline is 0.692 g·mL–1 (this assumption ignores additives). Also assume complete combustion. 2.The flask shown here contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.220 M NaOH. a. What volume of NaOH is needed to reach the...
