Form the following salts from the neutral elements and write the balanced reaction equation:

1. NaCl
2. MgO
3. KBr
4. Al₂O₃
5. Iron (II) oxide
6. Iron (III) oxide
7. Sodium oxide
8. Calcium oxide

---

Solution:

1. Na + ½ Cl₂ –> NaCl
2. Mg + ½ O₂ –> MgO
3. K + ½ Br₂ –> KBr
4. 4·Al + 3·O₂ –> 2·Al₂O₃
5. Fe + ½ O₂ –> FeO
6. 2·Fe + 3/2·O₂ –> Fe₂O₃
7. 2·Na + ½ O₂ –> Na₂O
8. Ca + ½ O₂ –> CaO
