A concentration gradient affects the direction that solutes diffusion. Describe how molecules move with respect to the concentration. How does size affect the rate of diffusion? Does polarity affect the rate of diffusion? Explain your answer. If a piece of celery is placed in a glass of pure water, are the celery cells hypertonic, hypotonic or isotonic compared to the water? In which direction will water move? What is the water potential of pure water? Why don’t red blood cells...

(0.3 point) Part 1 ii See Periodic TableSee Hint A solution is created by dissolving 12.5 grams of ammonium chloride in enough water to make 355 mL of solution. How many moles of ammonium chloride are present in the resulting solution? moles of NH4CI 0.233 When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid...

2. *D1* Salt water is plentiful on earth; natural supplies of fresh water, on the other hand, are dwindling while mankind's demands grow. One appealing solution to this imbalance is to remove the salt from ocean water by some means. Here you will investigate the energy input that is necessary to accomplish this task. Special membranes can be manufactured that allow water, but not ions, to pass through. By pushing such a membrane through salt solution, one can separate salt...

Once contaminated, polluted water sources must be treated or they represent a hazard to local residents. We have mentioned before that lead (Pb2+) ions are a particularly dangerous pollutant. How do we remove ions that we can't even see? Here our understanding of solubility can help. If we add an anion that forms an insoluble salt with Pb2+ ions, we could filter off the solid that forms and remove much of the lead contamination. Use what you know to help....
