Is combustion a chemical reaction? What is always true of a combustion reaction? What is enthalpy of combustion? How does a combustion reaction differ from other chemical reactions? Are combustion reactions exothermic? What's the balanced chemical equation for the combustion of carbon?
To recognize a combustion reaction, look for oxygen in the reactant side of the equation and the release of heat on the product side. Because it isn't a chemical product, heat isn't always shown. Sometimes the fuel molecule also contains oxygen. A common example is ethanol (grain alcohol)...

What are Combustion Reactions? - A combustion reaction is a chemical reaction which a fuel undergoes oxidation by reacting with an oxidising agent, resulting in the release of energy (usually in the form of heat).
Oxidation and oxidisation essentially describe the same chemical reaction process, where an atom, molecule, or ion loses electrons. This process is central to various chemical and biological systems, including combustion, rusting, and cellular respiration. The primary difference between the two terms ...
In mitochondria, pyruvate is oxidized to acetyl-CoA, and controlled "combustion" generates energy equivalent to two ATP molecules. The overall sum of the citric acid cycle can be represented as:Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 2 H2O → CoA-SH + 3 NADH + 3 H+ + FADH2 + ...
In a different example, the discharge through a resistor of a capacitor held at a DC potential for a while will be well-modeled by the usual exponential equation during the rapidly-changing portion of the discharge curve. During the “long tail” portion of the curve however, the capacitor ...
