Answer:

In the test tube, the two gases will diffuse towards each other. -When the two gases meet inside the test tube they react with one another and form a ring of Ammonium chloride that is white in color. ... This is because hydrogen chloride gas is heavier and diffuses slower than ammonium chloride.
