The reaction between magnesium powder and copper(II) oxide is highly exothermic and is represented by the following equation:
Mg+CuO→MgO+Cu \text{Mg} + \text{CuO} \rightarrow \text{MgO} + \text{Cu} Mg+CuO→MgO+CuWhat does this reaction show about the reactivity of copper compared to the reactivity of magnesium?
Why is this reaction described as a displacement reaction?
State two reasons why the term oxidation applies to magnesium in this reaction.
Although this reaction is highly exothermic, it only begins after initial heat energy is supplied. State how this heat energy is typically supplied in a laboratory demonstration.
