Vapors of ammonia (nh3) and hydrochloric acid (hcl) react to form a white cloud of nh4cl vapor. if these two gases are released into a tube from opposite ends will the white cloud of nh4cl form closer to the end of the tube from which nh3 was released or closer to the end of the tube from which hcl was released? explain your 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. 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.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

can you list the answers so i can answer
