The correct answer is Combustion

Which process refers to a rapid chemical combination of any substance with oxygen which produces energy?
Key Points

  • Combustion is a chemical process in which, a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer.

Which process refers to a rapid chemical combination of any substance with oxygen which produces energy?
Additional Information

  • Combustion is defined as a rapid exothermic reaction that liberates substantial energy as heat and flames as combustion reactions with the ability to propagate through a suitable medium.
  • Actually, combustion is a result of dynamic or time-dependent events that occur on a molecular level among atoms, molecules, radicals and solid boundaries.
  • Types of Combustion
    • Rapid combustion  
      • When combustion occurs rapidly, it is called rapid combustion.
    • Spontaneous combustion
      • The types of combustion in which material suddenly bursts into flames, without the application of any apparent cause are called spontaneous combustion. Eg, the Burning of phosphorus.
    • Complete combustion
      • Complete combustion is the mixture of fuel with oxygen without remaining fuel over time, friction and high enough temperature to ignite all the fuel components.
    • Incomplete combustion
      • Incomplete combustion is typically caused by inadequate air-fuel mixing, insufficient residence time, insufficient temperature and low total excess air.
    • Explosion
      • When a sudden reaction takes place with the release of heat and light and the evolution of a large amount of gas takes place it is called an explosion. Eg, firecrackers.

Solution

Combustion:(1) Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. (adsbygoogle = window.adsbygoogle || []).push({}); (2) The original substance is called the fuel, and the source of oxygen is called the oxidizer.(3) Three things are required in proper combination before ignition and combustion can take place —heat, oxygen, and fuel.(4) When substances react spontaneously with oxygen giving off heat and light, the heat released fuels the process further making the reaction violent and rapid.(5) If nothing is done to control this process, it takes the shape of a fire.Some examples are:(1) Burning of Wax candle.(2) Combustion of petrol in a car’s engine.(3) Burning of natural gas in a bunsen burner.Therefore, a chemical process in which a substance reacts with oxygen to give off heat is called combustion.

Which process refers to a rapid chemical combination of any substance with oxygen?

The rapid chemical combination of a substance with oxygen, involving the production of heat and light is called combustion.

What is a rapid chemical reaction with oxygen that produces energy?

combustion, a chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat and light in the form of flame.

Is a chemical process where oxygen is combined rapidly with a fuel to release stored energy?

Combustion is a complex series of chemical reactions, but from a physical standpoint may be described as the rapid combination of oxygen with a fuel, such as natural gas or wood, resulting in the release of heat.

What type of reaction involves a substance combining with oxygen and releasing energy?

Combustion Reactions A combustion reaction is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
