8. Propane (C 3 H 8 ) is a component of natural gas and is used in domestic cooking and heating. It burns according to the following reaction: C 3 H 8 + O 2 CO 2 + H 2 O a. Balance the equation representing the combustion of propane in air. (5 points) b. How many grams of carbon dioxide can be produced by burning 20.0 pounds of propane, the typical size of a BBG grill propane tank? Assume that oxygen is the excess reagent in this reaction. (5 points) 9. Hydrogen fluoride is used in the manufacture of Freons (which destroy ozone in the stratosphere) and in the production of aluminum metal. It is prepared by the reaction CaF 2 + H 2 SO 4 CaSO 4 + 2HF In one process 6.00 kg of CaF 2 are treated with an excess of H 2 SO 4 and yield 2.86 kg of HF. Calculate the percent yield of HF.
