Matter- Physical and Chemical Properties.Chemical properties of hydrogen: The chemical properties of hydrogen depend mainly on its bond dissociation energy. Due to high bond dissociation energy (436 kJ/mol), high energy is required to break the H-H bond. This makes hydrogen quite stable and unreactive at ordinary temperature. Majority of the reactions of hydrogen takes place …A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
