A chemist wants to resolve a particular amine, but she has only meso-tartaric acid on hand. She scans the lab inventory and finds several acids, but they are listed only by their common names, which she does not know or remember. Which of the following acids could she in principle use for the resolution of an amine: magic, maleic, malonic, malic, mandelic, meconic, muconic or myristic acids?

Calculate the concentrations of each ion present in a solution that results from mixing 49.6 mL of a 0.20M NaClO3(aq) solution with 25.3 mL of a .20 M Na2SO4(aq). Assume that the volumes are additive.
in a strongly acidic solution the amino acid lysine esists as the dication. as the pH is raised, what monocation is formed by the loss of a proton form the dication?
The hemodialyzer is 30cm long (between the blood inlet and blood outlet), and the blood inlet tubing and blood outlet tubing have the same diameter. What is the blood pressure drop (in units of mm Hg) from inlet to outlet if the hemodialyzer is or..
Calculate the ratio of equatorial to axial tert-butylcyclohexane at 25°C. Explain why the conformational equilibria for methyl, ethyl, and isopropyl substituents are comparable but the conformational equilibrium for tert-butylcyclohexane lies cons..
Imagine that you place a cork measuring 1.30cm x 5.50cm x 3.00cm in a pan of water and that on top of the cork you place a small cube of lead measuring 1.15cm on each edge. The density of cork is 0.235g/cm3, and the density of lead is 11.35g/cm3.
