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

Answer:

The constant density decreases

Explanation:

As the temperature of a solvent increases, the solubility of any gas dissolved in that solvent decreases.

For example:

when the temperature of a river, lake or stream is raised high , due to discharge of hot water from some industrial process the solubility of the oxygen in the water is decreased .The fish and the other organisms that live in the water bodies such as rivers, ponds, lakes etc can survive only in the presence of oxygen and decrease in the concentration of the water due to increased temperature can lead to the death of the fish and this may in turn damage the ecosystem.

In the above example, water is considered as the solvent and the oxygen is considered as the solute. When the temperature of the solvent that is water increases, the solubility of the gas that is oxygen in the solvent decreases.

Therefore the answer is decreases
