Respuesta :
during complete combustion carbon and hydrogen combine with oxygen (O2) to produce carbon dioxide (CO2) and water (HO2) during that time it is not completely oxidized producing soot or carbon monoxide
Answer: incomplete supply of oxygen
Explanation:
Combustion is a chemical reaction in which a fuel is reacted with excess supply of oxygen to result into complete oxidation of fuel to give carbon dioxide and water.
Example of complete combustion :
[tex]C+O_2 \rightarrow CO_2[/tex]
Incomplete combustion happens when the supply of oxygen is limited and thus fuel can not be completely oxidized , thus forming carbon monoxide.
Example of incomplete combustion :
[tex]C+\frac{1}{2}O_2\rightarrow CO[/tex]
