Combustion or burning is a chemical process, an exothermic reaction between a substance (the fuel) and a gas (the oxidizer), usually O2, to release heat. In a complete combustion reaction, a compound reacts with an oxidizing element, and the products are compounds of each element in the fuel with the oxidizing element. For example: CH2S + 6 F2 → CF4 + 2 HF + SF6 + heat Combustion - Rapid combustion. Rapid combustion is a form of combusti ...

Assuming perfect combustion conditions, such as an adiabatic (no heat loss) and complete combustion, the adiabatic combustion temperature can be determined. The formula that yields this temperature is based on the first law of thermodynamics and takes note of the fact that the heat of combustion (calculated from the fuel's heating value) is used entirely for warming up fuel and gas (e.g. oxygen or air). In the case of fossil fuels burnt in air, the combustion temperature depends on the heating value the stoichiometric air ratio λ the heat capacity of fuel a ...

Black powder consists of the granular ingredients sulphur (S), charcoal (provides carbon to the reaction) and saltpetre (saltpetre, potassium nitrate, KNO3; provides oxygen to the reaction). A simple, commonly cited, chemical equation for the combustion of black powder is: 2 KNO3 + S + 3C → K2S + N2 + 3CO2 A more accurate, but still simplified[1], equation is 10 KNO3 + 3S + 8C → 2K2CO3 + 3K2SO4See also:

Industrially, ethylene oxide is produced when ethylene and oxygen react on a silver catalyst at 200–300 °C. Pressures used are in the region of 1-2MPa. The chemical equation for this reaction is CH2=CH2 + ½ O2 → C2H4O The typical yield for this reaction is 70-80%, the major side reaction being combustion of ethylene to produce carbon dioxide. Several methods to produce ethylene oxide more selectively have been proposed, ...

Alkane - Reactions with oxygen. All alkanes react with oxygen in a combustion reaction, although they become increasing difficult to ignite as the number of carbon atoms increases. The general equation for complete combustion is: 2CnH2n+2 + (3n+1)O2 → 2(n+1)H2O + 2nCO2 In the absence of sufficient oxygen, carbon monoxide or even soot can be formed, as shown below for methane: 2CH4 + 3O2 → 2CO + 4H2O CH4 + O2< ...
