AIIMS 2019 Chemistry Thermal Decomposition MCQ Question

The reaction Ba(N₃)₂ → Ba + 3N₂ is a decomposition reaction where barium azide decomposes upon heating to yield barium metal and nitrogen gas (N₂). This reaction is well-documented in chemistry, confirming that pure nitrogen gas is indeed released when Ba(N₃)₂ is heated. Options (2) False and (3) Cannot be determined are incorrect because the reaction is both established and clear, while option (4) None of the above does not apply since option (1) is true. Understanding this reaction is essential for grasping the principles of thermal decomposition in inorganic chemistry.
