Combustion reactions always involve molecular oxygen O2. Anytime anything burns (in the usual sense), it is a combustion reaction. Combustion reactions are almost always exothermic (i.e., they give off heat). When organic molecules combust the reaction products are carbon dioxide and water (as well as heat).
People also ask, what are five examples of combustion?
Examples of Combustion
- Burning of Wood or Coal to heat your home.
- Burning of Petrol or Diesel to run your Car.
- Combustion of Natural Gas or LPG to cook for on your stovetop.
- For the production of energy in thermal power plants.
- Fireworks.
- There must be Fuel to burn.
- There must be Air to supply oxygen.
- There must be Heat (ignition temperature) to start and continue the combustion process.
Then, what type of reaction is combustion?
A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Combustion reactions must involve O2 as one reactant. The combustion of hydrogen gas produces water vapor (see figure below).
In order to burn this fuel, oxygen is needed, as it is with any fire. The waste products from the combustion process are water and carbon dioxide. Thus, we breathe because oxygen is needed to burn the fuel (sugars and fatty acids) in our cells to produce energy The air we breathe contains about 21% oxygen.
