{ The difference between incomplete and complete combustion of propane gas. By: Andrew, Raffy and Adrian

{{ Complete Combustion  C3H8 + 5O2 ---> 3CO2 + 4H2O  Propane + Oxygen-  Carbon Dioxide + water Incomplete Combustion  2C3H8 + 7O2  2C + 2CO + 8H2O + 2CO2  Propane + Oxygen  Carbon+ Carbon Monoxide + Water + Carbon Dioxide Equations

 Propane is a by product of gasoline, with the chemical equation C3H8  Propane is normally a gas but can be compressed to a liquid for transport  It is mainly used for barbeques, home heating, engine fuel and portable stoves. What is propane?

 Complete combustion takes place when there is excess oxygen  Incomplete combustion is when there is not enough oxygen for complete combustion.  When incomplete combustion occurs it forms water, carbon dioxide and carbon monoxide.  When complete combustion of propane occurs it only forms water and carbon dioxide. What are incomplete and complete combustion?

Chemical equation for incomplete combustion of propane Black=C Red=O (except in picture 2) White=W

Chemical Equation for complete combustion of propane + + Black= C Red = O White = H Blue = S

{{ Incomplete combustion  Lean Burn- occurs when there is less than 4% Propane, resulting in a flame that rises and extinguishes itself rapidly. Complete combustion  Rich burn- Occurs when there is more than 4% of propane. The end result being a much lager flame that is yellow in color. Evidence of chemical change

 Born Dec  He was a chemist that contributed to the development of explosives and liquefied petroleum gas.  He identified propane as a component in gasoline in  He also invented the under water detonator in 1907 Walter O. Snelling
