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