Is there any way, besides relying on taste or sending the product to a lab, to determine the concentrations of methyl and ethyl vanillins in artificial vanilla flavoring? I hear that a quality product can rival real vanilla extract in flavor in baking applications, but I have no way of determining quality, as ingredient lists are not useful; ingredient quantities are not listed.

Something that does NOT contain any animal products.
And as I say above, something which is deemed "safe". Safe may be an arbitrary term, but none the less...on today's market there are things the consumer needs to be careful with/about.

The fertilizer can be mineral, it can be synthetic, it can be organic, or it can be a combination of all three.mentioned categories

thanks

It was fishing a steam and it was getting pretty late at night when I heard a burning and looked up to see a little ball of fire which landed in the field next to me. I tried to find it, but it was too dark, so I went there the next day and finally found it, although I had to dig a little to get it. Anyway, the object looks like a large shinny ballbearing, but it feels like wet sand. The thing I don't understand is that it has no bounce. I threw it down on the pavement and still absolutely no bounce. It's like I'm throwing a magnet to another magnet. What kind of metal has this property?

the angle of tetrahedron shape is 109'28''.that is if u measure angle between tetrahedron's any two arms the angle would be 109'28''.it has one dominating pair having higher repulsive force compared to others that is indicated on the top of the atom while representing.considering this if we see the tetrahedron then u cant form it ,that is it has one angle more than 109'28''.considering 3 bonded arms being at 109'28'' with one arm they form a circle which can only make equal angles of 120'.if 3 arms are at 109'28'' then the angle between one bond wont be 109'28''.also in other plane wise considering we wont get the required angle.(one of my teachers agreed with what is said and others said my statement is not true and impossible )can any one tell me is it possible if iti is please explain the concept to me

I've been taking this chemistry course and I've noticed that the makeup of an atom looks a lot like our universe. The electrons are similar to our planet with them orbitting nucleus which is similar to the sun. Does anyone else find that interesting? Maybe someone can provide some more to this. I've just been wondering if anyone else notices the resemblance.
