Ammonium chloride is a solid formed when two gasses (NH3(g) and HCl(g) ) are put together. (--> NH4Cl(s) )
It may be called 'chemical sublimation', though literally speaking this is a 'contradictio in terminis'.
This looks like a solid cloudy smoke coming out of gas, very much the same as the pure physical sublimation of iodine gas to iodine crystals or the formation of hoar-frost (ice from humid freezing air)

Does ammonium chloride sublime?
yes it does (sort of, see below) other substances which sublime include dry ice(solid carbon dioxide), iodine, and naphthalene(substance found in mothballs). In the case of ammonium chloride, however, hydrogen chloride is driven off by the heat to give a mixture of gaseous ammonia and hydrogen chlroide. Condensation of the volatile acid and base regenerates ammonium chloride, so the process is actually a pseudosublimation.
To separate mixture of naphthalene and ammonium chloride by sublimation?
no because both sublime on heating
What is the observations on decomposition of ammonium chloride in an open container?
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
If ammonium chloride and sand under goes sublimationwhich solid sublimes?
If ammonium chloride and sand are heated or undergo sublimation, ammonium chloride being a sublimable substance sublimes and sand is left behind as the residue.
What is the difference between ammonium nitrate and ammonium chloride?
Ammonium nitrate is NH4NO3 Ammonium chloride is NH4Cl
Is NH4Cl sublime?
Yes, ammonium chloride can sublime.
How do you separate ammonium chloride from a mixture of ammonium chloride and potassium chloride?
Gently heat - ammonium chloride will sublime on a cold solid surface
Can ammonium chloride sublime from room temp?
no
Which separating technique is suitable for ammonium chloride and sodium chloride?
Sublimation - on gentle heating ammonium chloride will sublime. Sodium Chloride does not and has a high melting point.

What would happen if sodium chloride is taken instead of ammonium chloride during sublimation of ammonium chloride?
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)

What is the name for NH4Cl?
NH4Cl is ammonium chloride.
What is the name of the compound with the formula NaOCl?
There is no such substance as Na4Cl NaCl is sodium chloride. NH4Cl is ammonium chloride
Is sal ammoniac sublimatory substance?
Yes,sal ammoniac (ammonium chloride) is a sublimatory substance.
