The solution of potassium iodide (if it is not extremely diluted) is more dense.
The smell of naphthalene will likely be present in the mixture, although it may be less intense due to the dilution with chalk powder. The naphthalene odor may be detectable, especially in close proximity to the mixture.
Copper Sulphate (check your spelling) is a chemical compound. It can only be separated by chemical change, not by physical change. Therefore, it is not a mixture.
One way is to dissolve the ammonium chloride in water, then recover the ammonium chloride by evaporation; the naphthalene will not dissolve in water in any substantial quantity.
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
One possible way to separate naphthalene and potassium bromide is through sublimation. Naphthalene can be sublimed by heating the mixture, allowing it to vaporize and then condense back into solid form. Since potassium bromide does not sublime easily, it would remain in the solid state and can be separated from the naphthalene vapor.
Naphthalene can be separated from common salt by sublimation since naphthalene sublimes at a lower temperature than common salt. By heating the mixture, naphthalene will turn directly from a solid to a gas, leaving behind the common salt as a solid residue. The naphthalene gas can then be cooled and collected back as a solid.
Naphthalene can be separated from sodium chloride by sublimation. When the mixture is heated, naphthalene will sublimate, turning from a solid to a gas, and can be collected separately from the solid sodium chloride.

Does the mixture of potassium sulphate and water form a suspension
Add warm water to dissolve the KBr which is very soluble. This would become the aqueous layer and would be more dense and thus at the bottom. Add them to a sep funnel and decant. Evaporate the water off and you have the KBr. The remaining fluid in the sep funnel is npahthalene
The product of potassium sulfate and potassium hydroxide will be potassium sulfate and potassium hydroxide since they are already compounds. When water is added to the mixture, it will dissolve the compounds and create a solution. Adding potassium manganese to the solution would result in a mixture of all the substances present.

One way is to slurry the solid mixture with water. The ammonium chloride will dissolve and the naphthalene will not. Ammonium chloride can then be recovered by evaporating the water solution of it that is formed.

To separate naphthalene balls from sodium chloride, simply add water until all the sodium chloride is dissolved. Then either filter, or just pour off the solution, and the naphthalene balls will be left behind. Naphthalene is very insoluble in water, and sodium chloride is very soluble in water.
