2.by sublimation salts and amonia is separate
first: sedimentation and decantation with alum
hope it is helpful
plz mark as brainlest
To separate them follow the steps
First take the mixture in a beaker. Heat the mixture and cover it with the inverted funnelYou will see that the ammonium chloride get sublimated and had been collected at the cooler side of the funnel. Now scratch the ammonium chloride and collect it.
Now we have the non sublimated mixtureNow add some water to the mixture and stir it with the help of glass rodAfter sometimes the salt will get dissolved in the water. Now pour the solution through the filter paper. Sand will left behind in the filter paper as a residue and we will obtain salt solution as filtrate.
Pour the solution in a beaker and heat it. After sometimes you will see that water got evaporated leaving the salt behind in the beaker.
Air is a homogeneous mixture and can be separated by fractional distillation.
Air is compressed and liquified by increasing pressure and decreasing temperature.Then liquified air is allowed to warm up slowly in fractional distillation column and the gasses are being separated in different heights

make a solution of sand and salt in water then use a filter paper to filter it.Soil will be collected in paper and evaporate the water to get salt
air can be separated into the components by means of distillation in special units
explain with step by step answer
The two steps are:
(i) Heat the mixture. This will seperate the ammonium chloride from the solution, as it will evaporate
(ii) Make a solution of the remaining mixture and pass it through filter paper, salt which is soluble will pass through the filter paper while sand will remain back, as it is insoluble.
Hope that was helpful. Please mark my answer brainliest if it was help to you! Thank you!
