2024年11月15日 · combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.
Combustion - Wikipedia
Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.
11.6: Combustion Reactions - Chemistry LibreTexts
2022年9月21日 · 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 O 2 as one reactant. The combustion of hydrogen gas produces water vapor: 2H2(g) +O2(g) → 2H2O(g) 2 H 2 (g) + O 2 (g) → 2 H 2 O (g)
Combustion Reaction Definition and Examples - Science Notes …
2021年2月22日 · Combustion is a reaction between a hydrocarbon fuel (e.g., coal, propane, wood, methane) and molecular oxygen (O 2), producing carbon dioxide (CO 2), water (H 2 O), and heat. Heat provides the activation energy to start the chemical reaction.
Combustion Reaction: Definition, Characteristics & Examples
What is a Combustion Reaction? 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). The products of a combustion reaction …
Combustion - Chemical Reactions, Heat, Oxidation | Britannica
2024年11月15日 · Combustion, with rare exceptions, is a complex chemical process involving many steps that depend on the properties of the combustible substance. It is initiated by external factors such as heat, light, and sparks. The reaction sets in as the mixture of combustibles attains the ignition temperature.
An Introduction to Combustion Reactions - ThoughtCo
2024年8月17日 · A combustion reaction is a major class of chemical reactions, commonly referred to as "burning." In the most general sense, combustion involves a reaction between any combustible material and an oxidizer to form an oxidized product.
Combustion - Chemical Reactions, Heat, Oxidation | Britannica
2024年11月15日 · Combustion - Chemical Reactions, Heat, Oxidation: All flames can be classified either as premixed flames or as flames that burn without premixing. Flame combustion is most prominent with fuels that have been premixed with an oxidant, either oxygen or a compound that provides oxygen, for the reaction.
Combustion: what is it? - BBC Bitesize
Learn the definition of combustion, the equation for combustion and what a combustion reaction is in this BBC Bitesize KS3 Chemistry guide.
Combustion - Simple English Wikipedia, the free encyclopedia
Combustion is a reaction of a fuel with an oxidant to give out heat. The release of heat can produce light in the form of a flame. Car engines and rocket engines both work by combustion. Combustion in a Ferrari car motor is different from combustion in a rocket engine.
