Question

I.Give balanced equations for the decomposition reactions of the following compounds:-

1. Potassium nitrate
2. Ammonium hydroxide
3. Silver carbonate
4. Ammonium dichromate
5. Silver oxide
6. Lead carbonate
7. Potassium chloride
8. Copper carbonate
9. Zinc hydroxide
10. Calcium hydroxide
11. Ammonium nitrate
12. Phosphorus pentachloride
13. Ammonium nitrite
14. Washing soda
15. Red lead​

Answer 1

Answer:

1. 2 KNO3 ⇌ 2 KNO2 + O2

2. NH4OH → NH3 + H2O

3. Ag2CO3 → Ag2O + CO

4. 3(NH4)2Cr2O7  Cr2O3 + N2  + 4H2O

5. 2Ag2O → 2Ag + O2

6. PbCO3  → PbO + CO2

7. KCl → K+ + Cl- (KCl does not readily decompose, electrolysis needed)

    KClO4  → KCl  + 2 O2  ( Perhaps you meant chlorate not chloride)

8.CuCO3 → CuO + CO2

9. Zn(OH)2 → ZnO + H2O

10.Ca(OH)2 → Ca2+ + 2 OH

11. NH4NO3 →  N2O + 2 H2O

12. PCl5 → PCl3 + Cl2

13.NH4NO2→N2+2H2O

14. 2NaHCO3 → Na2CO3 + CO2 + H2O

15 .2Pb3O4 → 6PbO + O2
