Q1. Teach displacement reaction on blackboard
Ans. 
Displacement reaction involves the replacement of an element in a compound by another element.
• A more reactive element displaces a less reactive element from its compound.

• The displaced element forms a new compound with the displacing element.

• The reaction can be represented by a chemical equation.

• Example: Zn + CuSO4 -> Cu + ZnSO4

• In this reaction, zinc displaces copper from copper sulfate to form zinc sulfate and copper.
