Butane is a hydrocarbon fuel similar to gasoline, but lighter. It is sold as “bottled gas”, and is used in cigarette lighters. The chemical formula of butane is C4H10. Consider the complete combustion of butane. (Parts a and b are independent.) a. H for the reaction is -2.89x103 kJ/mol of butane. How much heat would be obtained by burning 850 g of butane? b. Write a balanced equation for the complete combustion of butane. Show phases.
a. 4.23x10^4 kJ b. 2 C4H10 (liquid) + 13 02 (gas) --> 8 CO2 (gas) + 10 H20 (liquid)
