Decomposition Reaction:
Ammonium carbonate ((NH₄)₂CO₃) decomposes when heated, producing ammonia (NH₃), carbon dioxide (CO₂), and water (H₂O) vapor:
(NH₄)₂CO₃(s) → 2 NH₃(g) + CO₂(g) + H₂O(g)
Effect on a Glowing Splint:
* Ammonia (NH₃): Ammonia is a colorless gas with a pungent odor. It will not support combustion, so the glowing splint would extinguish in the presence of ammonia.
* Carbon Dioxide (CO₂): Carbon dioxide is a colorless, odorless gas that does not support combustion. It will also extinguish a glowing splint.
* Water Vapor (H₂O): Water vapor is also not flammable and will not affect the glowing splint.
In Conclusion:
When ammonium carbonate decomposes, the gases produced (ammonia and carbon dioxide) will extinguish a glowing splint.
