Zinc
Copper carbonate solution(blue)
Displaced copper(brown)
Metals that are higher in the reactivity series will displace metals that are lower than them from their compounds

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.
