Answer : The number of oxygen atoms present on reactant side are, 4

Explanation :

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

Decomposition reaction : It is defined as the reaction in which the larger molecule decomposes to give two or more smaller molecules as a product.

The given balanced chemical reaction is,

2H_2O\rightarrow 2H_2+O_2

From the balanced chemical reaction we conclude that, there 4 atoms of hydrogen and 2 atoms of oxygen present on both reactant side and product side.

Hence, the number of oxygen atoms present on reactant side are, 4
