In a chemical reaction with which substance is hydrogen a reducing agent?

Hydrogen is a reducing agent for a group of substances and compounds that contain metal oxide. Since the metal is a stronger element of the compound, with greater electronegativity, it, using hydrogen as its natural oxidizing agent, completely restores its metal properties. The result of the process of such decay is always the formation of metal and water. An example of such a redox reaction is CuO + H2 = Cu + H2O
