- Answer Questions 6.79-6.82 based on the following scenario: Two solutions, A and B, are separated by a semipermeable mem- brane. For each case, predict whether there will be a net flow of water in one direction and, if so, which direction. 6.79 A is pure water and B is 5% glucose. 6.80 6.81 6.82 A is 0.10 M glucose and B is 0.10 M KCI. A is 0.10 M NaCl and B is 0.10 M KC1. A is 0.10 M NaCl and B is 0.20 M glucose.A 50X stock of Bradford reagent would have to be diluted to a 1X working solution prior to use. How much of the stock reagent solution and water are required to achieve this dilution? The final volume of the diluted solution is 1000 mL. Give your answers as whole numbers only (no decimal places). For example, if you think it would take 500 mL of reagent and 500 mL of water to make this dilution, then enter 500 and 500 in the appropriate spaces below. Volume of Bradford reagent required (in mL): Blank 1. Fill in the blank, read surrounding text. Volume of water required (in mL)Professor X mixed two solutions in a test tube and observed that the mixture was warm. He also tried to mix 50-ml each of the solutions in a 100-ml volumetric flask and found out that the total volume was less than 100 ml. He only has water, methanol, ethanol, and acetone in his table. From the following choices, what solutions did Professor X mix? a.acetone and water b.water and methanol c.acetone and ethanol d.methanol and ethanol
