What is produced from the complete combustion of alkanes?

The complete combustion of alkanes primarily involves the reaction of the alkane with oxygen, producing carbon dioxide and water as the main products. During complete combustion, each carbon atom in the alkane reacts with oxygen to form carbon dioxide, while the hydrogen atoms react to form water. This process requires a sufficient supply of oxygen, leading to the formation of fully oxidized products.

In contrast, incomplete combustion can produce carbon monoxide or soot (carbon) along with water, but that does not apply to complete combustion. The presence of insufficient oxygen would result in different products, which is not the case here. Thus, the production of carbon dioxide and water is characteristic of complete combustion, affirming that carbon dioxide and water are the expected products in this context.
