Combustion: A combustion reaction is an exothermic chemical

A combustion reaction is an exothermic chemical reaction between substances , usually including oxygen gas and accompanied by the generation of heat, energy, and light (flame). What is a Combustion Reaction? A combustion reaction is a reaction of a substance with oxygen gas to release relatively large amounts of energy . Because combustion reactions are often characterized by the presence of flames, a substance undergoing combustion is often said to be burning. When Coal (containing Carbon) is burnt in air, it reacts with oxygen present in air to produce Carbon Dioxide, heat and light. Example 2. When Magnesium ribbon is burnt in air, it reacts with oxygen in air to produce Magnesium Oxide + Heat + Light. In simple words, combustion is the process of burning a fuel in the presence of oxygen to release heat energy . This process is commonly used in cars, airplanes, power plants, industrial furnaces, and household cooking or heating devices.
