Combustion of Hydrocarbons

These flashcards cover key concepts related to the combustion of hydrocarbons, including definitions and differences between complete and incomplete combustion.

Complete Combustion

Occurs when there is a plentiful supply of oxygen, producing carbon dioxide and water as main products.

Incomplete Combustion

Occurs when there is insufficient oxygen, potentially producing carbon monoxide, soot, carbon dioxide, and water.

Carbon Monoxide

A toxic gas produced during incomplete combustion, posing serious health risks such as drowsiness and unconsciousness.

Hydrocarbons

Molecular compounds made up of hydrogen and carbon, examples include propane (C3H8) and butane (C4H10).

Combustion Reaction

A chemical reaction that occurs when a fuel burns in oxygen to produce combustion products, often releasing energy.

Energy in Combustion

The amount of energy released varies between complete and incomplete combustion, with complete combustion releasing the most energy.

Products of Complete Combustion

The primary products are carbon dioxide (CO2), water (H2O), and energy.

Products of Incomplete Combustion

Can include carbon dioxide (CO2), water (H2O), carbon monoxide (CO), and soot (C).

Flame Color in Complete Combustion

Complete combustion typically produces a blue flame, indicating a hotter and cleaner burn.

Flame Color in Incomplete Combustion

Incomplete combustion often results in a yellow, sooty flame, indicating a cooler burn.
