The complete combustion of a hydrocarbon would give carbon dioxide and water as the only products.
The complete combustion of a hydrocarbon would give carbon dioxide and water as the only products.
The products of a hydrocarbon combustion reaction are usually carbon dioxide (CO2) and water (H2O). Other by-products can include carbon monoxide (CO), nitrogen oxides (NOx), and sulfur oxides (SOx), depending on the composition of the hydrocarbon and the conditions of the reaction.

Assuming complete combustion, the products are carbon dioxide and water.
The combustion analysis of a hydrocarbon that produced 33.01 g of CO2 and 13.51 g of H2O can be used to determine the molecular formula of the hydrocarbon. By analyzing the amounts of carbon and hydrogen in the products, the ratio of carbon to hydrogen can be calculated, which can then be used to determine the molecular formula of the hydrocarbon.
When a hydrocarbon undergoes incomplete combustion, the primary products formed are carbon monoxide (CO) and soot (carbon particles), along with water (H₂O). Unlike complete combustion, which produces carbon dioxide (CO₂) as the main byproduct, incomplete combustion results in the release of harmful pollutants such as carbon monoxide, which is toxic. This type of combustion typically occurs when there is insufficient oxygen available for the reaction.
The general chemical equation for the complete combustion of a hydrocarbon is: Hydrocarbon + O2 -> CO2 + H2O For example, the combustion of methane (CH4) can be represented as: CH4 + 2O2 -> CO2 + 2H2O
The three necessary products are hydrocarbon molecules, oxygen gas, and an ignition source. Hydrocarbons are the fuel source, oxygen is the oxidizing agent, and an ignition source is needed to initiate the combustion reaction.
Combustion reactions always have O2 as a reactant. The other reactant is the thing being burned. If the thing being burned is a hydrocarbon, the products will be water and carbon dioxide.
