* Heat (energy) - This is the primary product of combustion, and what makes it useful for many applications.
* Light - Depending on the intensity of the combustion, light can be produced.
* Gases - The specific gases produced vary depending on the fuel and the availability of oxygen.
For complete combustion:
* Carbon dioxide (CO2) - This is produced when carbon-containing fuels are burned with sufficient oxygen.
* Water (H2O) - This is produced when hydrogen-containing fuels are burned with sufficient oxygen.
For incomplete combustion:
* Carbon monoxide (CO) - This is a toxic gas produced when there is not enough oxygen to completely burn the fuel.
* Soot (carbon particles) - This is produced when there is not enough oxygen to completely burn the fuel.
Other potential products:
* Nitrogen oxides (NOx) - These are produced from the nitrogen in the air when the combustion is at high temperatures.
* Sulfur dioxide (SO2) - This is produced when fuels containing sulfur are burned.
* Particulate matter - This is a mixture of solid particles and liquid droplets that are emitted during combustion.
It's important to remember that combustion is a complex process and the specific products can vary significantly depending on the fuel, the oxygen concentration, and the combustion conditions.
