Respuesta :
In the reduction-oxidation reaction given, Cu is reduced because it gained 2 electrons, on the other hand H2 is oxidized because it gained one electron. I hope this helps.
Answer: Copper is getting oxidized and hydrogen is getting reduced.
Explanation:
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of this substance is increased and the substance gets oxidized.
[tex]X\rightarrow X^{n+}+ne^-[/tex]
Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of this substance gets reduced and the substance gets reduced.
[tex]X^{n+}+ne^-\rightarrow X[/tex]
The given chemical reaction is:
[tex]Cu+H_2O\rightarrow CuO+H_2[/tex]
The half reactions for the given above chemical reaction is:
Oxidation half reaction: [tex]Cu\rightarrow Cu^{2+}+2e^-[/tex]
Reduction half reaction: [tex]2H^++2e^-\rightarrow H_2[/tex]
As, copper is loosing electrons. so, it is getting oxidized and hydrogen is gaining electrons. So, it is getting reduced.
