Question

Write any four chemical property of metal with the help of balanced chemical equation ?

Answer 1

Answer:

1. Metals react with oxygen to form Basic, Alkaline or Amphoteric oxides.

E.g. 2Fe+O₂→2FeO

2. Metals react with dilute acids to form its salt and evolve hydrogen gas.

E.g. Mg+2HCl→MgCl₂+H₂↑

3. Few metals react with bases to form metals' salt and liberate hydrogen gas.

E.g. Zn+2NaOH→Na₂ZnO₂+H₂↑

4. Metals react with a metal salt of low reactivity to form its salt and replace the other metal out.

E.g. Zn+CuSO₄→ZnSO₄+Cu
