Solution

Dear Student,

1. Acid react with metal to form salt and hydrogen gas.

2HCl + 2Na ----> 2NaCl + H2

2. Base react with metal to form salt and hydrogen gas.

2NaoH + Zn -->Na₂ZnO₃ + H₂ (sodium Zincates)

3. Metal oxide react with acid to give salt and water.
CuO + H₂SO₄ ----> CuSO₄ + H₂O

4. Non- Metal oxide react with base to give salt and water.

Ca (OH)₂ + CO₂ ----> CaCO₃ + H₂O
