C3H8 + O2 = CO2 + H2O is the chemical equation for C3H8 + 5 O2 = 3 CO2 + 4 H2O. This is the chemical reaction that occurs when propane or C3H8 burns in air or oxygen to produce carbon dioxide and water. In the presence of abundant oxygen, this chemical reaction involves the total burning of a hydrocarbon.
When a hydrocarbon, such as propane, burns in oxygen, the products are always water and carbon dioxide. For complete combustion to occur, a sufficient amount of oxygen or air is required. Hydrocarbon combustion is an example of an exothermic reaction where heat is released.
When there is insufficient oxygen or air, incomplete combustion takes place. C3H8 will undergo incomplete combustion if it is exposed to 4O2 instead of 5O2. This process produces water, carbon monoxide, and carbon. Carbon is emitted into the atmosphere in the form of soot and carbon monoxide, a toxic and hazardous gas.
Propane is an alkane, a type of hydrocarbon. It is a liquid, colourless gas that is compressed. Propane is also known as LPG and is classified as a clean-burning fuel. Commercial and domestic uses of propane include water heating, cooking, and heating. It can also be utilised as an alternative automotive fuel.
