The general equation for the incomplete combustion of decane (C10H22) with oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and carbon monoxide (CO) is:

C10H22 + O2 -> CO2 + H2O + CO

However, the exact stoichiometry and products formed may vary depending on the specific conditions of the combustion process, such as the availability of oxygen and temperature.
