Answer:

Step-by-step explanation:

A combustion is any reaction created between the combustible material (whether gaseous, liquid or solid) and the oxidizer. Oxygen has the ability to combine with various elements to produce oxides. There are oxidations that are extremely slow, but when it is fast it is called combustion. That is why the oxidizer is oxygen, and the fuel is usually hydrocarbons (organic compounds made up of only carbon and hydrogen atoms). These usually go into combustion with ease. In this process, the fuel oxidizes and gives off heat, and, frequently, light.

When a substance containing carbon and hydrogen (a hydrocarbon) undergoes complete combustion, or burning, oxygen is consumed and carbon dioxide is produced, and water. Incomplete combustion can also occur when part of the fuel does not react completely because oxygen is not enough. In complete combustion occurs: water vapor, carbon dioxide and caloric energy. On the other hand, if combustion is incomplete, carbon monoxide is produced.
