Answer:
NH₄Cl form closer to the end of the tube from which HCl was released.
Explanation:
Ammonia and hydrogen chloride gas react to form ammonium chloride water which can be seen by the formation of intensified fumes.
HCl + NH₃ ⇒ NH₄Cl
Since, the ammonia gas has a lower molecular weight as compared to that of hydrogen chloride gas. According to Graham's law of diffusion, the diffusion rate is inversely proportional to the square root of the molecular mass of the gas. <u>Thus, ammonia will diffuse faster as compared to hydrogen chloride gas. So, the white fumes will form at the side of the hydrogen chloride gas as it's diffusion will be slower and ammonia will diffuse fast and reaches to the gas.</u>
Kinetic energy of the particles is the measure of energy of the molecules when they are in motion. Kinetic energy is increased when phase change occurs from solid to liquid to gas. Solid has a rigid state which disables the particles to move unlike that in gas and liquid state where liquids can move more because of the spaces in between them.
Answer:

Explanation:
<span>The periodic table of elements is ordered by atomic weight from the top left to the bottom right. Each column is assigned a group, they can be either A groups or B groups. To determine the lightest element in the 1A group, locate the 1A column, at look at the top most element. In this case, H, hydrogen.</span>
