Question

in which reaction ammonium chloride on heating forms NH3 and HCl and on cooling again forms ammonium chloride

Answer 1

Answer:

When white solid ammonium chloride is heated strongly above 340∘C, it thermally dissociates into a mixture of two colourless gases. Those are ammonia and hydrogen chloride. After cooling, the reaction is reversed and solid ammonium chloride forms again. It is an example of sublimation.
