Combustion of hydrocarbons such as propane \( \left(\mathrm{C}_{3} \mathrm{H}_{8}\right) \) 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 propane into gaseous carbon dioxide and gaseous water.
\( \square \)
2. Suppose 0.250 kg of propane are burned in air at a pressure of exactly 1 atm and a temperature of \( 12.0^{\circ} \mathrm{C} \). Calculate the volume of carbon dioxide gas that is produced. Round your answer to 3 significant digits.
\( \square \) L
