Question

Combustion of hydrocarbons such as butane (C4H1o) produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosphere can trap the Sun's heat, raising the average temperature of the Earth. For this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide. 1. Write a balanced chemical equation, including physical state symbols, for the combustion of gaseous butane into gaseous carbon dioxide and gaseous water 2. Suppose 0.200 kg of butane are burned in air at a pressure of exactly 1 atm and a temperature of 12.0 °C. Calculate the volume of carbon dioxide gas that is produced Be sure your answer has the correct number of significant digits

Explanation / Answer

balanced reaction

2C4H10 + 13O2 ---> 8CO2 + 10H2O

NO of mole of C4H10 = 200/58.12 = 3.44 mole

No of mole of O2 = 63.1/32 = 1.972 mole

limiting reactant = C4H10

no of mol of CO2 = 3.44*8/2 = 13.76 mol

volume of CO2 gas = nRT/V

                 = 13.76*0.0821*285/1

               = 322 L
