Ammonium chloride appears to sublime but in this process solid NH4Cl actually (chemical) decomposition into ammonia and hydrogen chloride gas is involved. NH4Clsolid → NH3,gas + HCl,gas
NH4Cl (g) = NH3 (g) + HCl (g)
when ammonium chloride is heated its particles get converted into gaseous state i.e vapours of ammonium chloride due to sublimation.
since ammonium chloride is a subline solid, it gets converted into gaseous state directly without changing into liquid state
Ammonium nitrate is NH4NO3 Ammonium chloride is NH4Cl
sublimation
The products of the decomposition are different.
They are simply separated by Sublimation process , heat the mixture in an open container and put a large inverted funnel on container the Ammonium chloride becomes sublimed and its white crystals becomes deposited on the walls of funnel leaving the Lead chloride in container.
NH4Cl (g) = NH3 (g) + HCl (g)
The experiment will not work because sodium chloride does not sublime. Ammonium chloride appears to sublime upon heating. However, this process is actually decomposition into ammonia and hydrogen chloride gas. NH4Cl + heat → NH3 + HCl (Wikipedia)
when ammonium chloride is heated its particles get converted into gaseous state i.e vapours of ammonium chloride due to sublimation.
This is a chemical change (thermal decomposition).
NH4Cl is ammonium chloride.

Ammonium nitrate is NH4NO3 Ammonium chloride is NH4Cl
sublimation
Gently heat - ammonium chloride will sublime on a cold solid surface
Ammonium chloride is a molecule.
