PLEASE HELP I HAVE NO IDEA WHAT TO DO Use the balanced equation below to answer the question. A student begins a reaction with 200.0 grams of C7H603. Calculate the percent yield of the reaction if 231.0 grams of C9H304 is actually
produced.
C7H. O3 + C4H8O3 C9H204 + C2H4O2

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?

What will most likely happen when two bromine atoms bond together?
