Question

What three things are required for combustion?

Answer 1

Hint: The high-temperature exothermic chemical reaction is known as combustion. And this reaction is taking place between the fuel and an oxidant and there is a formation of oxidized gaseous products.

Complete step by step answer:
We also know that three things required for combustion are fuel, oxygen, and heat. The fuel is used to burn, the air is supplied through the oxygen and the heat is used to continue the combustion process. The heat is also called ignition temperature. Some examples of combustion which is used for energy are, burning petrol to run a car, combustion of LPG to cook, production of energy in thermal plants, burning of coal to heat the home and fireworks, etc.
We must have to remember that in a combustion reaction, there is a reaction between a fuel, that is hydrocarbon and oxygen will take place. By the reaction of oxygen and fuel, which produces heat and light energy which results in flame. And the reaction of combustion can be written as,
\[Hydrocarbon\, + \,Oxygen\, \to \,Heat\,energy\]
The combustion reaction of methanol can be written as,
\[2C{H_3}OH + 3{O_2} \to 4{H_2}O + 2C{O_2}\]
Here, methanol is reacted with oxygen and there is a formation of water and carbon dioxide.
And the combustion reaction is mainly divided into five types and that is, complete combustion, incomplete combustion, rapid combustion, spontaneous combustion, and explosive combustion.

Note: The three things primarily required for the combustion reaction are fuel, oxygen, and heat. Here the fuel is undergoing oxidation by the reaction of oxidizing agents and there is a formation of energy in the form of heat. Generally, a combustion reaction is a highly exothermic redox reaction. And there is a formation of oxidized fuel as the product.
