Question

2C2H5OH + 2Na → 2C2H2ONa + H2: Oxidation ::CuO+H2 → Cu+H2O: _______​

Answer 1

Explanation:

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.
