What is the approximate frequency of a photon having an energy 5 x 10-243?
(h= 6.6 x 10 -343•s)

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

c. orbital shape i hope this is correct

50.23 i believe is correct but don't quote me on that.
