Question

Does the reaction above satisfy the law of conservation of matter? Use details to support your work.

2H₂O₂=H₂+O₂

Answer 1

Answer:

No, the amount of matter of the reactants is not equal to the amount of matter of the products.

Explanation:

According to the conservation of matter the amount of matter of the reactants is equal to the amount of matter of the products. The given reaction is

$2H_2O_2=H_2+O_2$

In the reactant side there are $2\times 2=4$ molecules of hydrogen and $2\times 2=4$ molecules of oxygen.

In the product side there are 2 molecules of both hydgrogen and oxygen. So the reaction does not satisfy the law of conservation of mass.

The balanced reaction would be

$2H_2O_2=2H_2+2O_2$.
