Give examples of double displacement reaction

A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds. Here are some examples of this type of reaction:

1. AgNO 3 + NaCl → AgCl + NaNO₃
2. BaCl₂ (aq) + Na₂S₄ (aq) → BaSO₄ (s) + 2NaCl(aq)
3. 2NaCl + CaSO4 → Na₂SO₄+ CaCl₂
4. H₂SO₄ + 2LiOH⇌ Li₂SO₄ + 2H₂O
5. AgNO₃ + HCl ⇌ AgCl + HNO₃
6. Pb(NO₃)₂ + 2NaCl ⇌ 2NaNO₃+ PbCl₂
7. HCl + NaOH → NaCl + H2O
8. Al₂(SO4)₃ + 6NH₄OH → 2Al(OH)₃ + 3(NH4)₂SO₄
