Combustion of hydrocarbons such as methane (CH) 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 methane into gaseous carbon dioxide and gaseous water.
2. Suppose 0.250 kg of methane 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.
