If I'm not mistaken, I think what you are looking for is not Cr2O3, but CrO3 which is the acid anhydride of chromic acid. CrO3 is soluble in water and sulfuric acid. I wouldn't recommend you try chrome plating at home though. Since Chromium compound are toxic and carcinogenic. Also, you will have to dispose of the 'leftovers' properly. You cannot simply flush it away or dump it down the sink. It is illegal to do so since it is classified as hazardous waste. There are simply too many risks involved.

Did you try car repair shops, gas stations etc.. Battery acid for cars is around 33.5% sulfuric acid.

Yeah, I shouldnt have done that. Funny thing is that it had a delayed reaction. At first nothing was happening, I figured I hadn't added enough acid so I added some more. I then went to get a drink and then came back. I saw the thing smoking like crazy. I found out that the bluish green stuff was dissolved NO2. I was pouring it down the sink and NO2 gas started coming out. Well, thanks and hopefully I'll still be alive 24 hours from now.

Ok, I took a look at it now. I can see the white AgNO3 crystals and whats left of the liquid is a blue solution, probably copper. I'm going to leave it for a while, then take it out and filter it. Looks good Oh yeah, and would anyone happen to know how to neutralize or get rid of NO2 in the bathroom... thanks

Ah, but the silver I bought was apparently 99.9% pure. Got it off united nuclear. Could it that .01% make that big of a difference. Or might it me much more impure?

Could there be so much impurities that the solution turns dark green? Any idea what it might be?

Hi, I placed two silver disks in a beaker and added excess nitric acid to it, all of this was done in the balcony. I had my hot plate out there too. So i mix it and leave quickly and shut the balcony door. After the mixture heats up, a ton of NO2 gas starts evolving. After I while I started smelling it through the closed window, so I gather together two big fans, wait till the NO2 gas production has decreased, and open the balcony door. I aim the fans outside and turn them on full speed. Then i hold my breath and run out quickly (with a mask on of course) and turn off the hot plate. Now when I go back in I start breathing and the air was contaminated with NO2... I was breathing it in for like a minute. I quickly isolate the area, open all the windows.. shut all the doors to the area. Stop air conditioning and go into my room to write this. Now I held up the beaker to take a look at what was inside. All the silver had dissolved, the solution was a deep green color. I thought a solution of silver nitrate was supposed to be clear? Anyone have any idea on what the green color is? and wether I should probably see a doctor or not? Thanks

Just a shot in the dark here, but are you sure your hard drive isnt located at /dev/sda ? Depending on your distribution and kernel setup, if you have SATA drives they could be under /dev/sda and not /dev/hda. Check that. Also try removing it and plugging it into a different position .. secondary master/slave.. and try loading it there. Lastly, I would load a windows isntallation CD to see if it recognizes the hard drive at all.

Yup, and so would normal water.. Hydrogen Hydroxide.. Dihydrogen Monoxide.. etc.. check out this site: http://www.dhmo.org =D

I don't think that the bond in HHO are standard covanent.. In the Document it claims that the structure of HHO is (H x H)-O were the 'x' is a magnecular bond and that its caused by a change of the electric polarization of the water caused by their electrolzing box. They later state that the hydrogen atoms are polarized. Because the H atoms cannot remain polarized, the only 'solution' to that, they state, is for them to have the H atoms bond with opposing magnetic polarities. This polarization is also why the guy could apparently burn holes instantly through bricks.. "polarized H-atoms cause an induced polarization of the orbitals of the atoms of the brick, their consequential attraction to the polarized H atoms, and the latter rapid penetration within the deep layers of the brick structure". Now my question, is if that is true, how can it burn 'clean' .. why wouldnt a reaction occur.. and they say this instantaneous burning is because of the hydrogen.. but isnt the heat a product of the combustion of the gas? Check out page fourteen on that link i posted http://hytechapps.com/presentation/linked%20files/Hydro%20Tech/user%20added/Santilli,%20International%20Journal.pdf They say a sample of HHO gas is readily avaiable for free, to anyone who wishes to check it out.

If hydrino really exists, and the electrons in a hydrogen atom are at a lower energy level... would it mean that HHO gas is possible.. because hydrogen wouldnt need to give up its electron to acheive a lower energy state.. because it is already low.. mabe allowing it to accept an electron perhaps ? Hmm.. very intresting stuff .. mabe I'm way off =\

I found this scientific paper on their site: http://hytechapps.com/presentation/linked%20files/Hydro%20Tech/user%20added/Santilli,%20International%20Journal.pdf Haven't read it yet.. but I will get to it tommorow. Looks like it has all the details on the process of making the gas too.

Like I said earlier, cdrecord.exe would be the best application for the job. Its less than a megabyte, and you can launch multiple instances of it to burn on differnent drives at the same time. Its also free & open source.

If you insert a CD into the CD rom drive, you MUST eject it from the Operating System. It will not respont to you trying to press the eject key on the CD Rom drive. Most common distros work that way. Of course you can open an empty CD rom drive using the regular button.

Alot of drivers are compiled into the kernel or loaded as modules. If you arent gonna compile your own kernel, then i dont think you should worry too much about that. Since most distros precompile alot of wireless support into their kernels.

I thought gold was? I know they use it in real expensive cars and audio equiptment because its pretty much the best ?

If you want to stick with windows XP, I would first and foremost scrap the 'protection'. This isn't the usual advice i give people, but all of that will slow down your pc ALOT, and if you use your brain while on the internet, then you wont have a problem with viruses anyways. But yeah, I agree with Captain Refsmmat. Find yourself a good linux distribution and install it on your laptop. You will get far better performance than on windows.

Yes that's the book. If you want to learn C++, you can go directly to it and buy yourself a book on c++. I would recommend building on a foundation of C. Oh yeah, one more thing. Books will never teach you everything. You have to practice ALOT.

Yup, and it's actually a felony. Must be a real threat to society huh

I would do Iodine clock reactions. They never cease to amaze me. Google 'landolt reactions' or iodine clock reactions. It's a great display of how the concentration of a substance affects the rate of a reaction.

Chemfreak, It will do you no good. Neither will messing around with system files. Leave your operating system as it is. If you wish to get more speed out of your computer, upgrade your hardware.

Your best bet would be Microsoft Visual Studio 2003 .NET. I personally beleive that currently, its the best version. VS 6 is outdated and VS 2005 has alot of changes that are unnessicary and break regular c/c++ code. Another choice would be Borland's IDE, but borland doesn't have any Visual Basic IDE's. A good resource to have is MSDN. It's all avaliable online, but I would get me a copy of the MSDN DVD. There's a new one each month and I don't think they are expensive. It's a great resource. As for books I recommend taking a look at: Programming Win32 Under the API (With CD-ROM) Programming Windows, Fifth Edition I would also get a copy of Programming in C, Third Edition If you are planning on learning C/C++. One more thing. STAY AWAY FROM MFC.. or Visual C++.. =)

Hmm, well I guess it's a no to her then. The parents of the kids coming over won't allow the gasoline, which is why I was looking for another alternative.

I can't beleive I didn't make that out the first time I read it through.. Haha, That was a dead giveaway, I can't beleive I didn't notice that the first time. Thanks RyanJ
