Answer:
The given chemical reaction is not balance.
Explanation:
Given chemical reaction is not balance because,
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another.
In a chemical reaction, total mass on the reactant side is equal to the total mass on the product side.
We given that,
[tex]2 H_{2}O_{2} \rightarrow H_{2}O+O_{2}[/tex]
This is the unbalance reaction because in the reaction
In reactant side, the number of hydrogen atoms is 4 and oxygen atoms is 2.
In product side, the number of hydrogen atoms is 2 and oxygen atoms is 2.
In this reaction, We will multiply of the hydrogen atom by 2 in product side then the reaction becomes balance.
[tex]2 H_{2}O_{2} \rightarrow 2H_{2}O+O_{2}[/tex]
Hence, The given chemical reaction is not balance.
