4.12: Know the Possible Products of Complete and Incomplete Combustion of Hydrocarbons with Oxygen and Air



COMBUSTION: Chemical reaction that involves burning
s
COMPLETE COMBUSTION: Chemical reaction that involves burning with an unlimited supply of Oxygen so elements in fuel fully react with Oxygen
s
COMPLETE COMBUSTION OF HYDROCARBONS:
s
During the complete combustion of Hydrocarbons, Carbon Dioxide and Water will be produced:
s
  • Carbon will oxidise to form Carbon Dioxide
  • Hydrogen will oxidise to Water
s
EQUATION:
s

 Hydrocarbon   +   Oxygen   →   Carbon Dioxide   +   Water

s



*INCOMPLETE COMBUSTION: Chemical reaction that involves burning with a limited supply of Oxygen so elements in fuel does not fully react with Oxygen
s
INCOMPLETE COMBUSTION OF HYDROCARBONS:
s
During the incomplete combustion of Hydrocarbons, Carbon Monoxide and Water will be produced:


  • Carbon is released as soot
  • Carbon Monoxide is a poisonous Gas that reduces the capacity of red blood cells (haemoglobin) to carry Oxygen
s
EQUATION:
s

 Hydrocarbon   +   Oxygen   →   Carbon Monoxide   +   Water

  1. absolutely brilliant! i appreciate the work and effort it has helped me a lot! a small error just so others don't get confused where it says 'carbon dioxide is a poisonous gas...' it's carbon monoxide as it was clearly explained just a small typo
