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.
To separate a mixture of sand, table salt, iron filings, and naphthalene, you can use a combination of physical methods. First, use a magnet to attract and remove the iron filings. Next, dissolve the salt in water, filtering out the undissolved sand and naphthalene. Finally, evaporate the water from the salt solution to retrieve the salt, leaving behind the naphthalene, which can be collected through sublimation if heated gently.
Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
Use a magnet to remove the iron filings... Warm (do not boil) the remaining mixture to evaporate the naphthalene.
Naphthalene can be detected using gas chromatography or mass spectrometry techniques that can separate and analyze the compound's chemical properties and structure even if it's not visible. These methods can identify the presence of naphthalene by measuring its unique molecular characteristics. Additionally, specialized odor detection equipment can also be used to detect the distinctive smell of naphthalene that is often present even if it is not visible.
we will separate a mixture of sand pebbles and grassgrass - winnowingsand - winnowingpebbles - handpicking .
One way to separate naphthalene from sand is by sublimation. By heating the mixture, the naphthalene will undergo sublimation, turning into a gas and leaving behind the sand. The gas can then be collected and cooled back into solid naphthalene.
Sublimation can be used to separate naphthalene from sand. Naphthalene can be heated to change it directly from a solid to a gas, leaving the sand behind. The gas can then be collected and cooled to form solid naphthalene again.
Iron filings removed magnetically. Water will dissolve sodium chloride and suspend sand. Sand can be filtered out of the solution, and salt reovered by evaporation of water. Naphthalene can be removed separately if necessary by solution of mixture in alcohol.

You can pull the iron out with a magnet. Heat the mixture, taking appropriate safety precautions, and the naphthalene will sublime off and can be collected on a cold surface. Add the remainder to water, the salt will dissolve and the sand won't. Filter to collect the sand, and crystallize the salt from the filtrate.

by melting them through distillation
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.
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
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.
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.
