Addition of hydrogen chloride (HCl) to 1-isopropenyl-1-methylcyclopentane yields 1-chloro-1, 2, 2-trymethylcyclohexane. Intend a mechanism for the reaction. Demonstrate complete structures of the intermediates as well as use curved arrows to indicate electron flow in each step.
Suppose that you titrate a 3 g sample of orange juice and it turns out to contain only 95.5mg of vitamin C. Further, it took 32.45mL of DCP solution to reach the end point of the titration.
A student tried this identical procedure with a slight modification on a gel antacid. The student dissolved 3.00 mL in 25.00 mL of a standardized HCl solution containing 1.727 *10^-2 mol of HCl. The back titration of the excess HCl required 4.62 m..
Anfinsen studied the folding properties of the enzyme ribonuclease using the denaturants 2-mercaptoethanol and urea. How does each of these materials contribute to the unfolding of the protein,
What concentration of bezoyl peroxide (kd=1.45 x 10^6 L/mol at 60 C) would be needed to polymerize a 1M solution of styrene to a molecular weight of 125,000?

formaldehyde h2c o is known to all biologists because of its usefulness as a tissue preservative. when pure
describe a procedure by which you would prepare 250 cubic centimeter of aqueous sulphamic acid of accurately known
Consider the titration of 100.0 mL of 0.200 M acetic acid (Ka = 1.8 10-5) by 0.100 M KOH. Calculate the pH of the resulting solution after the following volumes of KOH have been added.
Serum taken from a patient being treated with lithium for manic-depressive illness was analyzed for lithium concentration. A reading of 414 units was obtained for the intensity of the 671 nm red emission line. Then 1.00 mL of a 11.9 mM Lithium sta..
