Read the descriptions below of two substances and an experiment on each, Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. • Sample A is 100 mL of a clear liquid. The density of the liquid is measured, and turns out to be 0.77 g/mL. The liquid is then cooled in the refrigerator. At 10.0 °C crystals begin to appear. The temperature of the liquid remains at 10.0 °C until all the liquid has crystallized. After all the liquid is frozen, the temperature starts to fall again, eventually reaching 6.2 °C. db • Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is ground to a fine orange powder and added to a 500 mL beaker full of water. The beaker is stirred vigorously. Some of orange powder settles to the bottom of the beaker, and some rises to the top and floats on the water. When the powder at both the bottom and the top of the beaker is filtered out, dried, and weighed, the total mass is measured to be 50.1 g. 2 199 pure substance ?
