what happens when the gas produced by heating chloroform with silver powder is passed into Ammoniacal silver nitrate solution​

Explanation:

Chloroform and silver powder react with each other and exchange the ions with each other to form acetylene molecules which are also called ethyne and silver chloride. The molecule C2H2is called acetylene which is a colourless gas with no odour.

2CHCl3+6Ag−→ΔC2H2+6AgCl

Note: The Ag powder is synthesized by reducing silver nitrate with glycerol and here glycerol acts as the solvent for the reaction. The above given reaction can be proceeded with tribromomethane (bromoform) or triiodomethane (iodoform) since the structure of iodoform and bromoform resembles chloroform.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
