What is the frequency of radiation
with a wavelength of 5.00 x 10-8 m?
in what region of the electromag-
netic spectrum is this radiation?

they are both synthetic elements

d

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".
