Combustion of Hydrocarbons

This set of flashcards covers key terms and concepts related to the combustion of hydrocarbons, focusing on complete and incomplete combustion, their reactions, and hazards.

Combustion

A chemical reaction that occurs when a substance reacts very quickly with oxygen to release energy.

Complete Combustion

Occurs when there is a plentiful amount of oxygen available to completely burn hydrocarbons, producing CO2 and H2O.

Incomplete Combustion

Occurs when there is a limited supply of oxygen, producing carbon dioxide, carbon monoxide, soot, water, and energy.

Hazards of Incomplete Combustion

Incomplete combustion can lead to the production of toxic soot and carbon monoxide, which can cause respiratory problems and poisoning.

Balancing Combustion Reactions

To balance complete combustion reactions: first balance the hydrogens, then carbons, and finally the oxygens.

Carbon Monoxide

An odorless and colorless gas produced during incomplete combustion, which can cause poisoning.

Impact of Incomplete Combustion in Cars

Incomplete combustion is frequent in automobiles, especially when idling, leading to harmful emissions.

Products of Incomplete Combustion

Can include carbon dioxide, carbon monoxide, soot, water, and energy.
