Question

Why sublimation of ammonium chloride is both physical and chemical change

Answer 1

BONJOUR...!✋


COMÓ ESTAS?


HERE'S YOUR ANSWER...!!!⬇⬇⬇

____________________________


● Sublimation is the process of changing of state from solid to gaseous state without changing into liquid state.

● Sublimation of ammonium chloride (NH₄Cl) is considered as both physical and chemical change.

● Sublimation of ammonium chloride (NH₄Cl) is a physical change because its state changes directly into gaseous state from solid state.

● Sublimation of ammonium chloride (NH₄Cl) is considered as chemical change because during its process of heating two new substances are formed. The two new substances are ammonia gas and hydrogen chloride gas. while heating ammonium chloride forms two new substances (ammonia gas and hydrogen chloride gas).

● Moreover, ammonium chloride is a white solid whereas, its products are gases.

Answer 2

Answer:

Some substances can undergo physical and chemical change:

Sublimation of NH4Cl ⇔ NH3 +HCl

when ammonium chloride is heated , it vaporizes to form gaseous ammonium chloride.

so it is a physical change .

Ammonium chloride is partially dissociated .

so it is a chemical change.

The products ammonia and HCl combine to fork NH4Cl . This also a chemical change
