Sublimation stands for the conversion of solid to gas without being converted to the liquid state. Bromine is already a liquid at room temperature and hence will not sublime. Ammonium chloride, camphor, iodine are solid at room temperature so can sublime (solid to gas). Hence, option D is correct.

WebThe mixture was made by combining 0.511g of naphthalene with 0.350 g of calcium carbonate. It was then placed into a mortar and ground up into a fine powder. Once the mixture was ground up, the sample was placed into a fairly large beaker (80 mL). Using the sublime approach to separate, the hardest task was finding the right height of the ring ...
