Vedclass · Answer

(A) When copper oxide $(CuO)$ is heated in the presence of dihydrogen gas $(H_2)$, a redox reaction occurs.In this reaction, $CuO$ loses oxygen to form copper metal $(Cu)$, which is a reduction process.Simultaneously, $H_2$ gains oxygen to form water $(H_2O)$, which is an oxidation process.The chemical equation for this reaction is: $CuO(s) + H_2(g) \xrightarrow{\Delta} Cu(s) + H_2O(g)$.Thus, copper metal is obtained as a product.
