Displacement reactions This is the competition between magnesium and copper for oxygen, when heated up together.

Magnesium wins the oxygen and copper metal is displaced.

Is magnesium higher or lower in the reactivity series?

The Thermite reaction

This is the competition between iron and aluminium for oxygen, when heated up together. Aluminium wins.

Is aluminium higher or lowerin the reactivity series?

Aluminium + Iron oxide Iron + Aluminium oxide + HEAT

The reaction gives off so much heat that the iron meltsand welds the rails together.
