Combustion of hydrocarbons such as ethane (C₂H₂) 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 ethane into gaseous carbon dioxide and gaseous water. 2C₂H(g) + 70₂(g) → 4CO₂(g) + 6H₂O(g) 2. Suppose 0.240 kg of ethane are burned in air at a pressure of exactly 1 atm and a temperature of 18.0 °C. Calculate the volume of carbon dioxide gas that is produced. Be sure your answer has the correct number of significant digits. L →0 00 X x10 Ś ?
A 6.00 L tank at 18.5 °C is filled with 19.5 g of dinitrogen monoxide gas and 16.9 g of sulfur hexafluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction of each gas. Be sure each of your answer entries has the correct number of significant digits. gas dinitrogen monoxide sulfur hexafluoride mole fraction 0 0 X S ?
