1.	Very pure nitrogen can be obtained by :A. Thermal decomposition of `NH_(4)Cl " and " NaNO_(2)`B. Treating aqueous solution of `NH_(4)Cl " and " NaNO_(2)`C. Liquefication and fractional distillation of liquid airD. Thermal decomposition of sodium azide.
Answer» Correct Answer - D Very pure `N_(2)` can be obtained by the thermal decomposition of sodium azide. `underset("Sodium azide")(2NaN_(3)) overset("heat") to 2Na + 3N_(2)`
