(5) a. Why quantum mechanics is needed by describing a relevant
experimental result (not Young’s experiment).
(Please just point out the particular experimental feature or features relevant to the need of quantum mechanics and do not discuss the experimental setups.)

Acetaminophen is a weaker acid than carbonic acid (H2CO3), but aspirin is a stronger acid than carbonic acid. prepare a flow diagram like the one in this experiment, showing a procedure that can be used to separate a mixture of sucrose, aspirin, and acetaminophen.

In this experiment column chromatography, two different elution solvent systems were used. Why? If their order had been reversed (i.e., 20:80 EtOAc–Hex was used first), how would the separation of the fractions have changed? |

Find the necessary confidence interval for the binomial proportion p. (Round your answers to three decimal places.)
A 90% confidence interval for p, based on a random sample of 985 trials of a binomial experiment which produced 592 successes.

penicillin is an irreversible "suicide" inhibitor of bacterical transpeptidase. if penicillin were present during a transpeptidase kinetics experiment, how would it alter the linewaver-burk plot. briefly justify your answer by discussing the effect of the inhibitor on Km and/or vmax
