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+H

2

⟶Cu+H

2

O

n the reaction H

2

is oxidized since it has lost electrons and Cu is reduced since it has gained electrons.
