Solution

Chemical Properties of Metals
1. Metals react with oxygen to form metal oxides.
Example: $2 M g + O_{2} ⟶ 2 M g O$
2. Metals react with water to form hydroxides.
Example: $C a + 2 H_{2} O ⟶ C a (O H)_{2} + H_{2}$
3. Metals react with acids to form salt and hydrogen gas.
$M g + H C l ⟶ M g C l_{2} + H_{2}$
4. Metals reacts with the salts of other metal, in which highly reactive metal displaces the less reactive metal.
Example: $Z n + C u S O_{4} ⟶ Z n S O_{4} + C u$
