Key Stage 4
Meaning
Complete combustion occurs when there is enough Oxygen to completely oxidise all of the atoms in a compound.
About Complete Combustion
- In the complete combustion of hydrocarbons and some other organic compounds the only products are Carbon Dioxide and Water.
- Methane + Oxygen → Carbon Dioxide + Water
\(CH_4 + 2O_2 → CO_2 + 2H_2O\)
- Ethane + Oxygen → Carbon Dioxide + Water
\(2C_2H_6 + 7O_2 → 4CO_2 + 6H_2O\)
- Propane + Oxygen → Carbon Dioxide + Water
\(C_3H_8 + 5O_2 → 3CO_2 + 4H_2O\)
- Butane + Oxygen → Carbon Dioxide + Water
\(2C_4H_{10} + 13O_2 → 8CO_2 + 10H_2O\)
- Ethene + Oxygen → Carbon Dioxide + Water
\(C_2H_4 + 3O_2 → 2CO_2 + 2H_2O\)
- Propene + Oxygen → Carbon Dioxide + Water
\(2C_3H_6 + 9O_2 → 6CO_2 + 6H_2O\)
- Butene + Oxygen → Carbon Dioxide + Water
\(C_4H_8 + 6O_2 → 4CO_2 + 4H_2O\)
- Methanol + Oxygen → Carbon Dioxide + Water
\(2CH_3OH + 3O_2 → 2CO_2 + 4H_2O\)
- Ethanol + Oxygen → Carbon Dioxide + Water
\(C_2H_5OH + 3O_2 → 2CO_2 + 3H_2O\)
- Propanol + Oxygen → Carbon Dioxide + Water
\(2C_3H_7OH + 9O_2 → 6CO_2 + 8H_2O\)
- Butanol + Oxygen → Carbon Dioxide + Water
\(C_4H_9OH + 6O_2 → 4CO_2 + 5H_2O\)
