I dunno how well it will work its huge but ill try. Its almost 600 pages but its really good.

Ive destroyed plenty of glassware in my time. If you distill HNO3 you wont die if you use rubber stoppers and such but they definately do literally melt. If you dont care about your rubber equipment go ahead and do it if your doing it for a very small amount. BUt generally dont do it its just stupid.

You need agar and petri dishes and your bacteria basically.

I thought ethanol was metabolized into H2O and CO2?

oh i have one on my computer its pretty good, i could probly send it to you if you give some kind of contact.

I rember we had this dilema before. With what you have I would try draining the idone as dry as possible, then getting ur florence flask vry cold on the neck with dry ice perhaps. That should keep most of the iodine from escaping and it should condense on the neck. From there u can just scrape it off

Hand grenades nor plastic explosives use KClO4. However it is used in smoke grenades.

humidity? sugar is really hygroscopic.

Actually you can light it with that, I tried it when the magnesium failed. As a matter of fact its directed here, http://www.ilpi.com/genchem/demo/thermite/ , to use kmno4 and glycerine.

I got an alcohol lamp and a pair of crucible tongs

wouldnt you use para and stuff because otherwise you could just read of silkworms name and draw it as a straight chain. Youd need to show it is a ring.

I wanted it for organic oxidation. Not the explosive kind, but the subtle alcohol too -COOH. And possibly for other organic things.

Ya i heard about being used in nuclear reactors pretty neat

guess they keep it in there to pull the heat away. Hmm interesting..

Is it possible to make chromic acid or chromic oxide/trioxide from ammonium dichromate?

ya she. but to find polarity you have to draw the molecule and find the shape (molecular geometry), then you compare the elctronegativities. For example, for H2O the shape is... bent planar. so then comapre the elctronegatives and you will see that the Oxygen is more electronegative and is thus more "negative" than the relatively positive Hydrogens. Thus, it is polar. For another compound such as AlH3, the molecule is a trigonal planar.

Thus, no matter what, it will not be polar because the charge will be distributed in no one direction.

For Aspirin it would be more complicated since it has no single shape.

Also, when aspirin hits acid pH in the stomach it actually can lose a hydrogen which can change the polarity to become more soluable. Since aspirin is polar in some spots, primarily the O bonds, its slightly soluable in water. C-H bonds are only slightly polar.

ryan there was no point to that post- he already knew it was slightly soluable . gosh

united nuclear has it, ebay as well. most chem suppliers. Its really not that bad, although it can be dangerous so can most things.

basically you wont be able to do this quietly if at all, and if you domanage to do it quietly it will also be at a high cost.

ya, just look online for tollens reagent, almost all the preperations call for NaOH.

I know KOH can be used but for some reason NaOH is prefered. Almost always NaOH is used to make this reagent. THe base is just needed to get the complex to form properly.

to make the goo stuff in toys you take polyvinyl alcohol, and sodium tetraborate and mix them. i dont rember the exact proportions but when hey are mixed they form stickly slime. adding morepolyvinylOH will make it more stick.

drill a hole and load it with some dynamite. just do it when everyones gone.

not in this case. thats only in a reaction, etc.

i think the oxide layer screwed thigns up. My teacher did the exact thing and it worked fine. It may take a while sometimes tho, just need somehtign to get it going.
