Answer 1

Answer:

1) Al2(SO4) 3

2) CaSo4

3)(NH4)2SO4

4) H2S

5)HCl

6)Ca3(Po4)2

7) FeCl2

Answer 2

Answer:

1. Aluminium sulphate = Al2(SO4)3

2. calcium sulphate = CaSO4

3. ammonium sulphate = (NH₄)₂SO₄

4. hydrogen sulphide = H₂S

5. hydrogen chloride = HCl

6. calcium phosphate = Ca3(PO4)2

7. iron sulphate = FeSO4

8. iron chloride = FeCl3

9. magnesium sulphate = MgSO4

10. magnesium hydroxide = Mg(OH)2

11. sodium hydroxide = NaOH

12. sodium chloride = NaCl

13. potassium hydroxide = KOH

14. aluminium oxide = Al₂O₃

15. iron oxide = Fe2O3

16. potassium chloride = KCl

17. zinc chloride = ZnCl₂

18. zinc sulphate = ZnSO₄

19. copper chloride = CuCl2

20. potassium carbonate = K2CO3

21. calcium carbonate = CaCO3

22. sodium carbonate = Na₂CO₃

23. cooper sulphate = CuSO4

24. sodium nitrate = NaNO3

25. potassium nitrate​ = KNO3

Hope it helped you........
