Question

During combustion what type of chemical reaction takes place

Answer 1

during combustion exothermic or hear evolving reaction take place

Answer 2

Heya friend,
Here is it:


Combustion reaction is a reaction in which a substance majorly hydrocarbon  reacts with oxygen and a large amount of heat is evolved in the form of heat and light.

In other words, we can also state that whenever a substance is burnt, combustion reaction takes place as oxygen is one of the major requirement for burning.

We can take the example of burning of methane($CH_{4}$(g) from the NCERT class 10 book only:-

$CH_{4}$(g) + 2 $O_{2}$(g) → $CO_{2}$(g) + $2 H_{2}O$(g)

(This  reaction can be found on Page number - 7 of NCERT science book)

This reaction is highly exothermic due to the evolution of a large amount of heat.


Thank you !!!
