Verified step by step guidance1
Identify the type of chemical reaction: Burning (combustion) of an organic compound like propanol (C3H7OH) in excess oxygen is a combustion reaction.
Recall that complete combustion of an alcohol produces carbon dioxide (CO2) and water (H2O) as products.
Write the general form of the combustion reaction for an alcohol: \(\mathrm{C_xH_yOH} + O_2 \rightarrow CO_2 + H_2O\).
Balance the combustion reaction by ensuring the number of carbon, hydrogen, and oxygen atoms are equal on both sides.
Conclude that the products of burning propanol in excess oxygen are carbon dioxide (CO2) and water (H2O).
