You are a chemical engineer that is responsible for synthesizing a new drug. You look at a series of potential chemical reactions that will make your drug along with their respective K values. What type of K value would you be looking for and why?
Given that the bond length of HBr is 1.41 A, estimate the dipole moment of this molecule by assuming a charge of 1+ on H and 1- on Br.

The plate is 10.00 cm thick (vertical dimension) and covered with water (n = 1.33) to a depth of 11.8 cm. Calculate the apparent thickness of the plate as viewed from above the water. (Assume nearly normal incidence of light rays.)
Describe, with equations, how a solution of sodium cyanide, NaCN, with hydrogen cyanide, HCN, functions as a buffer
Enzyme labeling can be used to map the structure of the active site of an enzyme using an affinity label, a molecule that is structurally similar to the substrate
Nitrogen-13 is used in tracers injected into the bloodstream for positron emission tomography (PET). The half-life of nitrogen-13 is 10.0 minutes. How much time is required for the activity of a sample of nitrogen-13 to fall to 14.2 percent of its..
If the first solvent pair for recrystallization is ethanol-water, what would happen if hexane replaced ethanol, to make the solvent pair of hexane-water
Draw the Lewis structures and determine which of these molecules has a central atom that violates the octet rule. Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom vi..
