Question

Identify the element undergoing oxidation in the given equation;
CuO + H2 → Cu + H20

a) cu b) h2o c) cuO d) h2​

Answer 1

The element is H2...because in the reactant side it is getting oxidised..

Plzz mark as brainliest ans..

Answer 2

H2 is getting oxidised cuz it’s charge on reactant side is 0
Whereas in product side it is -2
As overall charge on H20 is 0
Charge on O=-2
Charge on O+Charge on H2=0
-2+charge on H2=0
Charge on H2= -2
