Question

what happens when copper oxide is heated with hydrogen gas.why is this reaction called oxidation reduction reduction ​

Answer 1

Answer:

copper oxide is heated with hydrogen gas to form copper metal and water.The reaction is like this CuO+H2:-:-Cu+H2O. ln this reaction copper oxide is reduced to form copper as by definition removal of oxygen is called reduction.Hydrogen is oxidised to form water as addition of oxygen is called oxidation.So this reaction is called oxidation and reduction reaction
