Ammonium chloride decomposes when it is heated, as shown by the equation. The two gases produced are then allowed to cool.

ammonium chloride ⇌ \rightleftharpoons\,⇌ ammonia + hydrogen chloride

What happens as the gases cool?

[1]
A

The ammonia and hydrogen chloride stay as two separate gases

B

The ammonia and hydrogen chloride react to form ammonium chloride

C

The ammonia and hydrogen chloride react to form nitrogen and chlorine

D

The ammonia and hydrogen chloride both decompose into their elements
