Answer 1

Answer:

1. NH3 (Ammonia)

2. FeCl2 (ferrous chloride)(pale green)

3. As crystal is efflorescent therefore it will loose water and blue color of copper sulphate fades away.

4. H2O2-----> H2O + O2

Oxygen is the gaseous product

5. K + H2O ---> KOH + H2

Hydrogen is the gaseous product

6. Iron produces iron oxide and hydrogen gas

7. Sulphuric Acid

8. Ca+H2O----->Ca(OH)2 +H2

Calcium Hydroxide is the alkali product.

9. Al + KOH ----> H2 + K3AlO3(salt)

10. Fe+2HCl----> FeCl2(salt) + H2

11. Water gas is the gas obtained when steam is passed over white hot coke around 1000°C.

12. N2 + H2 ---(Fe)----> NH3

Ammonia is obtained.
