Answer 1

Answer:

e///a////b////d////

Explanation:

Answer 2

The correct order of separation techniques which should be employed to separate a mixture of sugar, sand and ammonium chloride is- e-a-b-d.

• Sublimation- The ammonium chloride can be separated from the mixture by the sublimation process. The mixture of sugar, sand and ammonium chloride is heated and ammonium chloride is converted into gaseous form and collected.
• Dissolution- Water is added to the mixture of sand and sugar. As sugar is soluble in water, it will be dissolved.
• Filtration- As sand is insoluble in water, it can be separated from sugar and water by filtration process. The sand will remain on the filter paper while sugar and water will go through filter paper.
• Evaporation- The sugar can be separated from water by evaporation process. The water will be evaporated and sugar will remain in the vessel.
