Ag+ will precipitate in HCL solution as AgCl, but as for Ag(NO3), i am not so sure.

You might be looking for information on alchemy, not chemistry.  The two fields of study are very seperate these days.  Of course, modern scientits could turn lead into gold by nuclear fusion, or turn heavier elements into gold by fission- neither process seems practical.

Congrats, I am working on my thesis too.  There is PDA (potato dextrose agar), V8 agar (made from guess what, V8) and many others.  Each is designed for a specific purpose.  I am not an expert on this, but try a search engine.

You can't. Alchemy is a myth. Without nuclear reactions, you can't turn lead into gold, or any element into any other element.

It can be easily produced in a high molecular weight form through ring-opening polymerization using a stannous octoate catalyst, but for laboratory demonstrations tin(II) chloride is often employed.\nand you meant polyLactic acid

One way is to plate metal as a substitute for chromium. Rhodium is often referred to as hard chrome.

arent rubber bands toxic? they werent made for chewing gum was!

It probably contains zinc since it ends the way it does. This is something that should work: \nhttp://www.inhousepharmacy.com/mens-health/saw-palmetto.html

ok so.  first   balance the equation. shouldnt be too hard. 2Cr  3Cl2   and     2CrCl3 \nchromium u dont have to worry about cuz itz excess. you have 125g of Cl2 though. so you have to find   out how many moles that is. by dividing by the molar mass. so once you find out the   number of moles reacting  and then  find out the according number of moles of CrCl3    that are formed. in this case  its the same number    so    then   once you know the number of moles. you    find the   mass by  multiplying by the molar mass. and there u go

Guar gum is a polysacharide (a long chain made of sugars) made of the sugars galactose and mannose.\n\nSome other familiar polysacharides are starch and cellulose, which are made of long chains of the sugar glucose.\n\nGuar gum comes from the endosperm of the seed of the legume plant Cyamopsis tetragonolobus. Cyamopsis tetragonolobus is an annual plant, grown in arid regions of India as a food crop for animals.

We have used the Chromium technique when making slides but for our purposes we found this doesn't work as the Chromium diffuses into gold over several days. You can use a technique such as allowing the clean glass slide to soak in PDMS and a solvent for several hours, rinsing, dry (preferably clean air line), and then place into a vacuum/heat chamber and allow the gold to coat the surface of the slide.  Done!  Check out some scholarly articles...more detailed explanations are available in experimental sections of research journals.

Look here:\n\nhttp://jewelrymaking.about.com/od/solderinginformation/a/032806.htm\n\nand here:\n\nhttp://alchemy.chem.uwm.edu/amalgamator/NCW/ncw2001/results.html\n\nto get the following:\n\nThe pickle, used in the soldering metal process is a sodium bisulfate based solution. This pickle is particularly good for gold. Other metals use different pickles. For example, "Copper and copper alloys can be pickled in sulfuric acid solutions with the addition of an oxidizing agent (for heavy scales) such as chromic acid, nitric acid, ferric sulfate or sodium dichromate. NOTE: Chromic acid and dichromate require treatment for hexavalent chromium. Chromic acid or dichromate solutions tend to passivate the substrate and require activation prior to plating. Activation is commonly carried out in 5-10% sulfuric acid solution or 10-20% hydrochloric acid solution. If the latter is used to interchangeably pickle steel parts and copper parts, the dissolved copper must be closely controlled to avoid a typical problem. The dissolved copper will eventually plate out on the steel parts and cause adhesion problems."\n\nI hope this helps.  Be careful.

nope. coatings are usually made of water soluble materials which could be easily excreted once disintegrated in the gi tract. maybe he/she is referring to shellac, the ones used in sugarcoating.
