Question

when copper oxide is treated with hydrogen gas copper is produced along with water. the balanced chemical equation for the given reaction is cuo +h;— cu + ho which substance is oxidized in the given reaction?


A.H2 B.Cu C.H2O D.CuO​

Answer 1

Answer:

cuo+h2=cu+h2o this reaction represents. In the reaction CuO + H2 →Cu + H2O. In the compound CuO(s), the oxidation number of O is -2 and the oxidation number of Cu is +2.
