When hydrogen chloride (HCl) and ammonia (NH₃) vapors react, they form solid ammonium chloride (NH₄Cl):

HCl(g) + NH₃(g) → NH₄Cl(s)

A swab soaked with HCl solution was inserted into one end of a glass tube (1 cm diameter), and, simultaneously, a swab soaked with NH₃ solution was inserted into the other end, so that the swabs were 10 cm apart. The distance that each vapor traveled could be determined because, at the point they made contact, a white ring of NH₄Cl formed. The reaction was done at different temperatures. The time it took for the precipitate ring to start to form and its distance from the HCl swab were measured for each trial. The table for the data collected during the experiment is shown in the table.

Organize these options into the right categories.

Categorize the following

temperature

distance from the HCl swab

time for the percipitate ring to start forming

distance between swabs

timing of swab placement

type of solution used

Independent Variable

Dependent Variable

Controlled Variable

When hydrogen chloride (HCl) and ammonia (NH₃) vapors react, they form solid ammonium chloride (NH₄Cl):

HCl(g) + NH₃(g) → NH₄Cl(s)

A swab soaked with HCl solution was inserted into one end of a glass tube (1 cm diameter), and, simultaneously, a swab soaked with NH₃ solution was inserted into the other end, so that the swabs were 10 cm apart. The distance that each vapor traveled could be determined because, at the point they made contact, a white ring of NH₄Cl formed. The reaction was done at different temperatures. The time it took for the precipitate ring to start to form and its distance from the HCl swab were measured for each trial. The table for the data collected during the experiment is shown in the table.

Based on the results, which of the following graphs best shows the relationship between the temperature and the distance of the ring from the HCl swab?

The distance that each vapor traveled could be determined because, at the point they made contact, a white ring of NH₄Cl formed. The reaction was done at different temperatures. The time it took for the ring to start to form and its distance from the HCl swab were measured for each trial.

The same experiment was done again, but this time longer tubes were used so that the distance between the swabs could be varied for each trial. The table for the data collected during the experiment is shown.

If a trial in Experiment 2 had been performed with the swabs 25 cm apart, the distance from the HCl swab to the ring would most likely have been closest to:

a)

8 cm

10 cm

c)

12 cm

d)

14 cm

The student concluded that NH₃ diffuses at a greater rate than HCl. Do the results of experiments 1–2 support her conclusion?

a)

No, the data shows that as the distance between swabs increased the ring formed farther away from the HCl.

b)

Yes, the data shows that there is a positive correlation between temperature and distance the gas traveled.

c)

No, the data shows that the time it took longer for the ring to form when the temperature was hotter.

d)

Yes, the data shows that both time and distance increased as the distance between swabs increased.
