1. A cup of coffee is made in the morming by pouring boiling water over ground-up coffee beans held in a special piece of paper and by collecting the brown liquid that comes through. Which techniques of the five described in the Introduction section is used in the preparation of the drink? 2. A tablespoon of sugar is added to the cup of coffee and the solid disappears. What makes up the “cup of coffee" now? Is this a mixture? 3. What is taking place during the process of sublimation? How is this process different from evaporation?

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. g of a coarse grey powder with a faint unpleasant smell. 15. g of the powder is put into a funnel lined with a sheet of thick paper. Distilled water is poured slowly over the powder. All of the powder disappears, and the water under the funnel turns a deep purple. . Sample B 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 continues to decrease as more crystals form, until at 6.2 °C the liquid is entirely solid. Is sample A made from a pure substance or a mixture? If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide." Is sample B made from a pure substance or a…

When you boil diethyl ether, the diethyl ether turns to diethyl ether vapour. If you boil 4 g of diethyl ether, how much does the resulting diethyl ether vapour weigh? Mass = g
Four different solutions were prepared in the laboratory. One was prepared by dissolving 28 g of potassium permanganate in enough water to make 200 milliliters of solution. Another was prepared by diluting 100ml of 5.8 molar of potassium permanganate solution to 500 mL. The third solution was prepared by aliquoting 5 mL each from the first two solutions and diluting it with 50mL. The fourth solution was prepared by adding thirty-five grams of potassium permanganate with 50 mL sample of the first solution and diluting it to 100mL. For the final solution, 18 mL aliquot from the first solution, 12 ml aliquot from the second solution 41 mL aliquot from the third solution and 19 mL of the fourth solution were mixed. What is the molarity of the fourt solution? What is the concentration of the final solution?
