Question

what is redox reaction? identify the substance that gets oxidised and the substance that gets reduced in the given reaction. CuO +H2=Cu+H2O​

Answer 1

Answer:

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. In redox reaction the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

In the reaction : CuO+H2⟶Cu+H2O 

n the reaction H2  is oxidized since it has lost electrons and Cu is reduced since it has gained electrons.

Answer 2

Explanation:

As a copper is reduced from copper oxide so copper oxide is reducing agent.

...

Cuo+ H20= CU + H20.

1) Here the oxidized substance is

= H20. As the oxygen is added to hydrogen.

2) Here the reduced substance =Cu.

3) Oxidizing agent is copper oxide.
