Catalyst
which of the following statements are true about the given reaction a it is the decomposition reaction and endothermic in nature be it is a displacement reaction see it is a decomposition reaction exothermic in nature sea it is a photo decomposition reaction and exothermic in nature​

Answer 1

Explanation:

To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. As the oxygen collects in the top of the gas jar, it pushes the water out.

A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
