* Fuel: Different fuels have different compositions. For example, pure hydrocarbons like methane will primarily produce carbon dioxide and water when burned completely. Fuels containing other elements, such as sulfur, will produce additional products like sulfur dioxide.
* Oxygen availability: If there is enough oxygen present for complete combustion, the primary products will be carbon dioxide and water. However, if oxygen is limited, incomplete combustion occurs, and carbon monoxide can be formed along with other products like soot (carbon particles).
* Temperature: The temperature of the combustion process also affects the products formed. Higher temperatures can lead to the formation of more carbon monoxide.
In summary:
* Complete combustion: Abundant oxygen, primarily produces carbon dioxide and water.
* Incomplete combustion: Limited oxygen, produces carbon monoxide, soot, and other products.
Therefore, while carbon dioxide and monoxide are common products of combustion, they are not always formed, and their relative amounts depend on the specific conditions.
