$$2C_{18}H_{36} + 49O_2 \rightarrow 36CO_2 + 36H_2O$$
In this equation, two molecules of \(C_{18}H_{36}\) react with 49 molecules of oxygen (\(O_2\)) to produce 36 molecules of carbon dioxide (\(CO_2\)) and 36 molecules of water (\(H_2O\)). This reaction represents the complete combustion of \(C_{18}H_{36}\), meaning that all of the carbon atoms in the fuel are converted into carbon dioxide and all of the hydrogen atoms are converted into water.
