Answer 2

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 2O

⟶Cu+H 2O

n the reaction H 2 O

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