Question

Conduct an experiment to observe the speed of diffusion of two substance

Answer 1

Answer:

Explanation:

In the experiment to study diffusion using hydrogen chloride (HCl) gas and ammonia (NH4Cl), the experiment is conducted as follows:

------------------------------------------------------------------------------------------------------

The required apparatus are:

- 2 Cotton buds

-A test tube

-2 Glass stoppers

-Ammonia solution

-Hydrogen Chloride acid

------------------------------------------------------------------------------------------------------

Procedure for the experiment: 

1)Soak 1 cotton bud into ammonia solution and fix on one end of the testube.

2)Soak the other cotton wool on concentrated hydrochloric acid and fix on the other end of the test tube.

3)Use the glass stoppers to close both ends of the test tubes.

------------------------------------------------------------------------------------------------------

The results of the experiment:

-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. 

- The ring is formed closer to the end where hydrogen chloride is. This is because hydrogen chloride gas is heavier and diffuses slower than ammonium chloride. 

This experiment is used to test the rate of diffusion of gases and the speed at which they diffuse.

Answer 2

The test to determine the speed of distribution of two objects is:

• Diffusion is the complete movement of anything (for example, atoms, ions, molecules, energy) usually from a high concentration area to a low concentration area.

• The gas distribution rate is opposite the square root of the volume (density).

• Therefore, the standard formula for distribution is: distribution rate ∝ 1 / d e n s i t y.

• So if the material is lite, it will have faster distribution rates.
• The main reason for this phenomenon is that the speed of atoms or molecules directly affects the distribution rates.
• Due to the high temperatures, the speed of the molecules increases, due to which they increase the distribution rates over time.
