Question

Explain why a mixture of copper oxide and magnesium reacts when heated while there is no reaction when a mixture of copper and magnesium oxide is heated

Answer 1

we know that magnesium is more reactive than copper when magnesium react with copper oxide it displaces opper from copper oxide

Answer 2

Answer:Magnesium will displace copper from the copper oxide creating the reaction but copper cannot displace magnesium from its oxide hence no reaction

Explanation:Magnesium is higher than copper in the reactivity series haence can displace copper from its oxide but copper is below magnesium in the reactivity series hence cannot displace it from its oxide
