Asolution containing 94.4 ml of carbon tetrachloride, ccl4, dissolved in 250.0 ml of nitrobenzene, c6h5no2, was placed in the freezer, which dropped the temperature to 0°c. did the solution freeze at that temperature? if so, at what temperature? the density of ccl4 is 1.59g/cm3. the density of c6h5no2 is 1.2 g/cm3.

no, it would freeze at 5.7°c.

no, it would freeze at 26.74°c.

no, it would freeze at -21.07°c.

no, it would freeze at -16.61°c.

yes, it would freeze at 0 °c.

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?
