Question

Nitrogen is obtained by the thermal decomposition of :

• A. NH4Cl
• B. NH4NO3
• C. AgNO3
• D. None of these

Answer 1

Answer: (D)

None of these

Answer 2

NH4Cl gives NH3, NH4NO3 gives N2O and AgNO3 gives NO2.

(1) NH4Cl $\overset{\quad\Delta\quad}{\rightarrow}$ NH3 + HCl

(2) NH4NO3 $\overset{\quad\Delta\quad}{\rightarrow}$ N2O + 2H2O

(3) AgNO3 $\overset{\quad\Delta\quad}{\rightarrow}$ Ag + NO2 + 1/2O2
