2. Conc.H2SO4 is added to Table salt.
3. Dilute Hydrochloric acid reacts with Magnesium sulphide
4. Dilute Nitric acid reacts with Zinc sulphite.
5. Ammonia solution is added first dropwise, till in excess to Copper chloride
solution.
6. Ferric carbonate reacts with dilute Sulphuric acid.
7. Sodium hydroxide solution is added first dropwise, till in excess to Zinc nitrate
solution.
8. Caustic soda is heated with Ammonium chloride​

Answer 1

Explanation:

1. 2Al+2NaOH+2H2O→2Na2AlO2+3H2

2.Conc.H2SO4+2NaCl→2NaSO4+2H2SO4

3.MgSO3+2HCl→MgCl2+H2O+SO2

4.ZnS+H2SO4→ZnSO4+H2S

5.CuSO4+2NH4OH→Cu(OH)2+(NH)42SO4

6.FeCO3+H2SO4→FeSO4+CO2+H2O

7.Zn(OH)2+2NaOH→Na2ZnO2+2H2O

8.NH4Cl+NaOH→NH3+NaCl+H2O
