Example 1: Copper & Zinc

• In this reaction, copper is replaced/displaced by zinc:
  
  Zn + CuCl2 --> ZnCl2 + Cu
  
  

Example 2: Bromine & Chlorine

• In this reaction, bromine is replaced/displaced by chlorine:
  
  Cl2 + NaBr --> NaCl + Br2
  
  

Example 3: Hydrogen & Magnesium

• In this reaction, hydrogen is replaced/displaced by magnesium:
  
  Mg + HCl --> MgCl2 + H2
  
  

Example 4: Zinc & Hydrogen

• In this reaction, zinc is replaced/displaced by hydrogen:
  
  Zn + H2SO4 --> Zn SO4 + H2
  
  

Example 5: Copper & Silver

• Cu(s) + 2AgNO3(aq) -> 2 Ag(s) + Cu(NO3)2(aq)
  
  In this reaction, a copper strip is dipped into a silver nitrate solution. The copper replaces/displaces silver atoms, resulting in the creation of copper nitrate and the precipitation of silver metal crystals.
