Answer 1

In certain firework , potassium nitrate breaks down into potassium oxide, nitrogen and oxygen . This is an example of a ÇÒMBUSTION REACTION. The opposite process is a SYNTHESIS REACTION.



I hope it helps u!

Answer 2

Answer:

This reaction is an example of a decomposition reaction more specifically a  Combustion Reaction, and the opposite reaction is a synthesis reaction.

Explanation:

A decomposition reaction is a reaction in which the compound breaks into simpler compounds or elements. In this case, the energy for decomposition is given by burning so it is also a combustion reaction.

The potassium nitrate on heating breaks down into potassium oxide, nitrogen, and oxygen.

The equation for this reaction is :

$2KNO_3 (s) - > 2 KNO_2 (s)+O_2 (g)$

In the synthesis reaction opposite of this happens and more complex compounds are formed. Synthesis reactions are often exothermic.
