검증된 단계별 안내1
Recall that alkanes are hydrocarbons composed only of carbon (C) and hydrogen (H) atoms.
Understand that complete combustion means the alkane reacts fully with oxygen (O_2), producing the most oxidized forms of carbon and hydrogen.
Recognize that carbon in alkanes is fully oxidized to carbon dioxide (CO_2) during complete combustion.
Recognize that hydrogen in alkanes is fully oxidized to water (H_2O) during complete combustion.
Therefore, the two typical products formed during the complete combustion of alkanes are carbon dioxide (CO_2) and water (H_2O).
