5) A tetrahedral shape will sometimes have rotational symmetry and sometimes will not. A CH, will have rotational symmetry. Write the chemical formula for a
tetrahedral shaped compound that WOULD NOT have rotational symmetry and
draw its Lewis structure below. (HINT - How could you change out some of the
elements of CH, slightly to make it asymmetrical?)

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?
