The gas formed when ammonium trioxonitrate (V) is heated with sodium hydroxide is?
hydrogen
nitrogen (IV) oxide
oxygen
ammonia
Explication
When ammonium trioxonitrate (V) (NH₄NO₃) is heated with sodium hydroxide (NaOH), ammonia gas (NH₃) is released, along with water and sodium nitrate. The reaction can be represented as:
NH₄NO₃ + NaOH → NH₃ + H₂O + NaNO\(_3\)
