Afeed solution of 10,000 lbm at 130°f containing 47.0 lb feso4/100 lb water is cooled to 80°f, where feso4 7h20 crystals are removed. the solubility of the salt is 30.5 lb feso4/100 lb water. the average heat capacity of the feed solution is 0.70 btu/lbm- f. the heat of solution at 18°c is -28.47 btu/lbm feso4 7h20 crystals. if 5% of the water in the feed is vaporized, calculate the yield of crystals and the amount of heat removed from the crystallizer.

You mix the pks of succinic acid are 4.21 and 5.64. how many gramsa graduate student at sdsu wants to measure the activity of a particular enzyme at ph 4.0. to buffer her reaction, she will use a buffer system based on one of the acids listed below, which acid is most appropriate for the experiment? of monosodium succinate (fw = 140 g/mol) and disodium succinate (fw = 162 g/mol) must be added to 1 l of water to produce a solution with a ph 5.28 and a total solute concentration of 100 mm? (assume the total volume remains 1 liter, answer in grams monosodium succinate, grams disodium succinate, respectively.) volumes of 0.05 m nah2po4 and 0.05 m na2hpo4 (pk's for phosphoric acid are 2.15, 6.82 and 12.38). which of the following best describes the resulting solution?
