The heat of combustion of heptane and isooctane are -4501 kJ/mol and -5100 kJ/mol, respectively. Isooctane (2,2,4-trimethylpentane, pronounced iso-octane) is a pretty good model for the complex mixture of hydrocarbons that is gasoline. The density of these two liquids (essentially the same for all liquid hydrocarbons) is 0.7 g/mL (kg/dm3). What is the heat of combustion of one gallon of the two liquids? Are they essentially the same or quite different? Why? a. b. The U.S. Congress (our representatives) mandated...

Ahmadi, Inc. has been manufacturing small automobiles that have averaged 50 miles per gallon of gasoline in highway driving. The company has developed a more efficient engine for its small cars and now advertises that its new small cars average more than 50 miles per gallon in highway driving. To test this hypothesis at 98% level of confidence, an independent testing service road-tested 64 of the automobiles. The sample showed an average of 51 miles per gallon. Assume that the...
