Question

CuO +H2 cu +H2o Name the reluctant in the above reaction​

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.
