Verified step by step guidance1
Understand that complete combustion of a hydrocarbon means the hydrocarbon reacts fully with oxygen (O_2) to produce the most oxidized forms of its elements.
Recall that hydrocarbons are composed of carbon (C) and hydrogen (H) atoms.
In complete combustion, carbon atoms are fully oxidized to carbon dioxide (CO_2), not carbon monoxide (CO) or elemental carbon (C).
Hydrogen atoms in the hydrocarbon are oxidized to form water (H_2O).
Therefore, the products of complete combustion of any hydrocarbon are carbon dioxide (CO_2) and water (H_2O).
