Question

State the difference between complete and incomplete combustion.

guys it's really very urgent please help​

Answer 1

Difference between Complete Combustion and Incomplete Combustion:

Oxidant:

• Complete combustion occurs when there is a sufficient and adequate supply of the oxidant, while incomplete combustion occurs when there is an insufficient and inadequate supply of the oxidant.

Hydrocarbon combustion

• Complete combustion of hydrocarbons will result in the production of carbon dioxide and water, while an incomplete combustion of hydrocarbons will result in the production of carbon monoxide and water.

Flame:

• In incomplete combustion a yellow or orange flame is usually produced while in complete combustion a blue flame is produced.

Smoke:

• Incomplete combustion produces smoke as a result of the reaction, while complete combustion does not produce smoke as a result of the reaction.

Energy production:

• Incomplete combustion produces less energy than complete combustion because not all the reactants are consumed in the reaction, while in complete combustion all the reactants are consumed.

Environmental impact:

• Carbon dioxide produced by complete combustion can contribute to global warming while carbon monoxide and smoke produced from incomplete combustion contributes to air pollution.
