A sample of 11.7 moles of silver bromide is reacted with 8.6 moles of sodium thiosulfate to produce
sodium silver thiosulfate and sodium bromide. Using
the balanced equation below, predict which is the
limiting reactant and the maximum amount in moles
of sodium bromide that can be produced.
AgBr + 2Na2S2O3 + Na3Ag(S203)2 + NaBr
A. sodium thiosulfate, 4.30 moles
B. sodium thiosulfate, 8.60 moles
C. sodium bromide, 5.85 moles
D. sodium bromide, 11.7 moles

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?
