  1. The difference between incomplete and complete combustion of propane gas.

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

  3. 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?

  4. 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?

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

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

  7. Incomplete combustion 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. • Lean Burn- occurs when there is less than 4% Propane, resulting in a flame that rises and extinguishes itself rapidly. Evidence of chemical change

  8. Born Dec 13 1880 • He was a chemist that contributed to the development of explosives and liquefied petroleum gas. • He identified propane as a component in gasoline in 1910. • He also invented the under water detonator in 1907 Walter O. Snelling
