It's not that I can't imagine any way this could be done, it just seems unlikely. The next piece of evidence came in the form of a copper nodule on eBay, nowa sample right here. It looks rather similar to these nodules except it's not as round, but it has no flat side and it...

The process of reduction of metal cations via electric current in order to form a metal layer on the electrode is called electroplating. In the case of the silver electrodes, oxidation of anions via electric current is carried out. Answer and Expl...
Answer to: Copper (Cu) is element 29 on the periodic table. A sample contains 9.18 x 1022 atoms of Cu. Calculate the amount (moles) of Cu in this...
So at least if you can't impress them with your brilliance, dazzle them with lab equipment.I have been working on a plating solution that is made completely from items available in the home, and without using concentrated acids or bases. It is mighty tempting, I'll tell you, to augment...
