Question

write one significant Observation for the action of heat on ammonium chloride​

Answer 1

Answer:

mark me the brainliest answer

the process of conversion of solid to gas directly without leaving any residue by the process of heating is called sublimation.ammonium chloride is a sublimate so therefore once it is heated it converts into ammonium vapour

Answer 2

Dissociation of Ammonium Chloride occurs on the application of heat into Ammonia and HCL hydrogen chloride.

● This dissociation of Ammonium Chloride is a reversible reaction where on cooling again Ammonia and HCL combined to form a white precipitate and which settle down at the bottom of the test tube.

● The combining occurs at the top layer where the temperature is low and precipitation occurs at the bottom of the test tube.
