Explain the chemical properties of metals.
Chemical Properties of Metals
1. Metals react with oxygen to form metal oxides.
Example: 2Mg+O2⟶2MgO
2. Metals react with water to form hydroxides.
Example: Ca+2H2O⟶Ca(OH)2+H2
3. Metals react with acids to form salt and hydrogen gas.
Mg+HCl⟶MgCl2+H2
4. Metals reacts with the salts of other metal, in which highly reactive metal displaces the less reactive metal.
Example: Zn+CuSO4⟶ZnSO4+Cu
