Answer : The given equation are not balanced equation.

Explanation :

Balanced chemical equation : It is defined as the number of atoms of individual elements present on the reactant side must be equal to the number of atoms of individual elements present on the product side.

The given chemical reaction is,

This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of oxygen are not balanced and the molecule are missing on the product side.

So, in order to balanced the chemical reaction, the molecule are added on the product side.

Thus, the balanced chemical reaction will be,
