http://en.wikipedia.org/wiki/Hexamine\nHexamine is a product of reaction of 6 moles formaldehyde and 4 moles ammonia ((CH2)6 N4))\nBut be careful cause hexamine may be absorbed through the human skin and some people have an allergic reaction under the influence of  (dusty) hexamine and skin colors red but, when exposure is stopped, the symptoms disappear soon without harmful consequences.\nHexamine is sensitive to humidity, but it is not hygroscopic substance.Packing must be appropriate.Hexamine may even cake at low humidity or by pressure and heat.

They make it now but it is in liquid form. It is called alcohol. You don't have to have a script for it. It is available over the counter

Insoluble amines can be made soluble by adding acid to the solution.  This forms the ammonium salt which is ionic and soluble.  Therefore the answer would be b, HCl.\n\nA similar strategy can also be used by adding base to carboxylic acids and phenols with low solubility.

This is a selective way to produce cupper of cupper hydroxides by leaching hydroxide and elecrtowinnig as:\nCu(OH)2(s) = Cu+2(aq) + 2 OH–(aq) \nCu+2(aq) + 4 NH3(aq) = Cu(NH3)4+2(aq)\n\nand [Cu(NH3)4]2+ is better agent than [Cu(H2O)6]2+ in (aq) solutions for this.

There are many you could choose.  These may not be the most efficient, but I'm just going with initial thoughts here.\n\n1.  Aniline -> benzamide\nDiazotise the aniline and trap out with CO2 to form benzoic acid, then make an amide.  Probably easiest way is to make the acid chloride with (COCl)2 and then treat with NH3.\n\n2. Bromobenzene -> 1-phenylethanol\nForm phenylmagnesium bromide by treating bromobenzene with magnesium in diethyl ether, and react with ethanal.\n\n3. Butanal -> 1-chloropropane\nMany ways to do this, none of them nice.\n\nReduce butanal to butanol, de-hydrate, perform a reductive oxonolysis to give 1-propanol and then do a chloro-dehydroxylation with SOCl2 or something like that.\n\nAlterantively you could oxidise and do a Barton-Crich de-carboxylation and trap out the radical with NCS, although this method may not be too successful.\n\nHope these quick ideas help.

Use cocoa powder.  To stretch it mix it with your talcum powder.

Here's how u can do it:\n\n(Step 1): Take an asbestos sheet of any diameter you like depending upon the size u want to make.\n\n(Step 2): Take a long jar and build a mountain with modelling clay with a hollow(but not very deep) pit.\n\n(Step 3): Leave it in the sun for drying.\n\n(Step 4): Get Ammonium Dichromate (NH4)2Cr2O7 from a chemical shop.\n\n(Step 5): Place a small amount of Ammonium Dichromate into the pit and drop a lighted camphor in the pit. You will see that Ammonium Dichromate increases in its volume, sparks are evolved and a green coloured lava flows out of the pit.\nThis is Chromium Oxide and the reaction can be represented like this:\n(NH4)2Cr2O7 --> Cr2O3 + 4 H2O + N2\n\nNote: Ammonium Dichromate and camphor are both toxic chemicals. Have a teacher around you to help u and keep a bucket of water near u.

Go to the link provided.  This is the acetate salt.  Thionine is a cation so it will have to be presented with a positive charge.  My suggestion is to replace the acetate with "X-" in your presentation.\nGood luck on your project.

Try a pharmaceutical chemist. They may be able to obtain a small quantity for you.

1/8 cup borax laundry detergent\n1 1/2 cup hot water\n1 cup white elmers school glue\n1 cup hot water \nMix borax with hot water. Stir until dissolved. Mix glue and water. put 1/2 cup plus 2 tablespoons of glue mixture in a medium Ziploc bag and add 2 drops food coloring. Add 1/4 cup borax mixture. Squish the bag to mix the ingredients well. Soon you'll have a slime. Put in small containers overnight. Children have a lot of fun playing with it and it's not messy

I'm assuming you're asking so you can make some so I posted a recipe for it below. The link below takes you to several other recipies for it.\n\n\nSILLY PUTTY   \n\nElmer's Glue\nLiquid cornstarch (available in a grocery store)\n\nMix equal parts of starch and glue (5 teaspoons of each is generally a good amount to work with). If the mixture is too stiff, add more glue. If the mixture is too runny, add more starch. Wipe off any excess starch and you have silly putty! Try stretching it, pulling it apart sharply, or bouncing it on the floor. CAUTION: It sticks to rugs! (From the "Sticky Business" Room at The Children's Discovery Museum, Acton, MA)

mix it...let NaCl dissolve in water...then let the mmixture evaporate or perhaps bring the mixture into a boil 'til you can see the formation of crystals...   try it... i've encountered such experiment in my chemistry class... im not quite certain of the procedures though...it's two years ago...cant remember it well...^_^

The Simple 16-Step Guide To Triangular Construction\n\n# 1. Obtain a crisp packet, or optionally one of the many alternatives to a crisp packet which may be utilised as the basis for this operation. These particular instructions are based on the assumption that the packet you find can be considered rectangular by somebody of sane mind. These can usually be purchased at all the most relevant shops.\n\n# 2. Relieve the packet of any extraneous contents that it may have, such as, for example, crisps.\n\n# 3. Ensure that you are now the owner of an empty and flat crisp packet (or similar item- see #1) by placing the packet in question on a floor, and stamping up and down on it for a timespan of roughly five minutes. Your stamps should be mostly in a constant vertical direction for fear of irrevocably ripping the packet, and should not greatly exceed five minutes for fear of causing it internal bleeding. This process is catalysed by the use of a hard, even an unc*rpeted, floor, and if you are a very fat person wearing heavy shoes.\n\n# 4. You are now ready to make a Crisp Packet Triangle. If you suffer from high blood pressure, it might be a little excessive to have a few medically-trained personnel on hand should you collapse during this, but such precautions will not greatly impede the Triangle making process.\n\n# 5. Find which side of the packet you are using is shorter than the other side. If this is your first time making a triangle, it might be best to use a ruler (if you are a man, be sure not to exaggerate the inches), but if you are a more experienced triangular, it may be done by visual consideration alone.\n\n# 6. Fold the packet over relative to the shorter side, so that the length of the shorter side is halved whilst the length of the more lengthy side remains the same. If you are using a crisp packet and you find that the 'spine' gets in the way of making the two sides of the fold even, do not worry. On this fold (but only on this fold) it does not matter if the two 'halves' of the fold are not equal.\n\n# 7. Repeat the process described in #6- in the same words, fold the packet over relative to the shorter side, so that the length of the shorter side is halved again whilst the length of the more lengthy side is still completely unaffected. On this fold, the lengths should meet and the halves should be equal, otherwise the triangle making procedure could be severely impinged.\n\n# 8. Remove any air that may have inadvertantly crept into the packet whilt you weren't looking. This is done by running caressing fingers along the soft packet, the soft nerves of your tender touch feeling every ripple and breath of the soft, tender skin. If you should now feel the need to go and lie down, be sure to place the packet under a heavy book before you go so that the air doesn't get back in again. On the subject of air, it is important that by this stage in the proceedings, you have not forgotten to breathe for any long period of time.\n\n# 9. If you want this easy, you could wait a month or so now until pictures are installed on this web page because describing this bit isn't easy. In effect, you should hold the packet lengthways and fold one of the ends (of the long side) through a right-angle around a diagonal pivot in the middle so that you end up with a right-angled shape. If you don't understand, get a geometry teacher to do it for you, but be sure not to listen to what they are saying with their mouths because it might prove fatal to your brain in your head. A rough illustration of this (the folding, not the geometry teachers' deadly mouths) can be seen in Fig 1.\n\nFig. 1 (above)\n\n\n# 10. Take the half of the packet that you have just folded through a right angle, and with any amount of care and precision that you choose to apply to the task, fold it underneath the triangular area just formed, so that it is now forming the other right-angle with the side that you didn't fold. Again
