sand and ammonium chloride are insoluble in water but sodium chloride is soluble in water .ammonium chloride sublimates. so you first heat the mixture in a beaker covered with a watch glass then the ammonium chloride will accumulate on the watch glass leaving a mixture of sodium chloride and sand you then dissolve the mixture then filter using a beaker and a filter paper the filtrate is salt solution while the residue is sand you then evaporate the salt solution to remain with salt
The correct answer is B. The solute is the substance that can dissolve. So, alcohol is the solute.
No because as the creation of the of the rock from the lava is considered construction not destruction
