Greenhouse gases n 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 liquid dodecane into gaseous carbon dioxide and gaseous water. ロロ ローロ 2. Suppose 0.220 kg of dodecane 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. Round your answer to 3 significant digits.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
