A gas chromatography column containing a (diphenyl)0.65(dimethyl)0.35polysil oxane stationary phase is used to separate the following molecules. Place the molecules in the order they will elute from the column. A list of retention indexes for several molecules can be found here. -butanol 1-nitropropane 2-pentanone -octane - nonane -decane

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".
