2a, 17a dimethyl etiocholan 3-one, 17b-ol

and

2a,17a-dimethyl-17b-hydroxy-5a-androstan-3-one

From the looks of it, it is the same. But I was curious if there was something that I was missing here?

if you get silver nitrate on something, be it skin, clothes, etc, it will produce a localized brown stain after it has been exposed to sunlight. i have some of it on my skin now, can't argue with the results! i was just wondering what the reaction is... does the Ag+ and/or NO3- form some other compound? why does the brown stain remain localized, if the compound is so water-soluble (and the human body is mostly water)?

no wikipedia answers, i was totally dissatisfied by their information.

Why does ice sometimes pop out of your ice water, or other type of iced beverage? It's almost like it completely snaps, and shoots out of the cup. Where does the energy for this come from???

(a)How many unpaired electrons are there in the valence shell?
(b)Carbon is known to form four covalent bonds when forming molecules. Give a possible reason for this. Is there a connection between the number of unpaired electrons in the valence shell and the number of covalent bonds?

I don't believe oil came from dead dinosaurs. I think it came from the decaying of dead vegetation. If so, why can't we produce it in the laboratory? Then we could have big factories spewing out the stuff. Energy crisis GONE: Trade deficit GONE: Overpopulation GONE (By not teaching the Chinese and Indians how to drive their new cars, and just turn them loose: That's how!).

Can anyone please tell me, is benzoic acid present in human urine. I know that it appears as part of the structure of hippuric acid in mammals such as horses and was wondering if it is also in human urine as we produce a small bit of hippuric acid daily.

Many thanks in advance for your comments.
