Select all statements that are true for sn1 reactions. (a) formation of the carbocation is the rate-determining step (rds) (b) the reaction rate depends upon the concentration of both the nucleophile and the electrophile (c) reactions at chiral carbons proceed with inversion of stereochemistry (d) none of these statements are true for sn1 reactions (e) carbocation rearrangements are never observed

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?

Calculate the ratio of h+ ions to ohβ ions at a ph = 7. find the concentration of h+ ions to ohβ ions listed in table b of your student guide. then divide the h+ concentration by the ohβ concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to ohβ ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of ohβ ions at a ph = 7? mol/l what is the ratio of h+ ions to ohβ ions at a ph = 7? : 1
