I have a bucket full of soda-lime glass bead blasting material that has flour gold mixed in it. I can't remove the gold by means of mechanical separation and was wondering if there's a chemical method to dissolve the soda glass leaving the gold behind. I am willing to send samples to whom ever can help and you may keep the gold that you extract in return for information. I can see the gold with a jewlers loop. This is a lucrative opportunity for whoever can assist me. I have already turned in over 10k$ worth of gold that was larger pieces but now the gold is very tiny and sifting is not doing the trick anymore. I'm looking at a mercury method but I'm interested in dissolving the soda-lime glass chemically. TIA

Think xyz axis in space. Assume there are two Hydrogen atoms on the x axis. Assume they are heading toward each other along the x axis. Then what do you predict will happen? A Hydrogen molecule will necessarily be formed or not? How about assuming the initial states of the two Hydrogen atoms to be both in 1S state? Or rather how about assuming them to be 2Py and 2Pz states each? I think the latter case seems more favorable for forming a Hydrogen bonding. Because the electrical charge distribution might form a net attraction between all of the participant electrons and protons upon collision. And if the bonding were to be formed, then after bonding are the protons oscillating? After the bonding, are the electron clouds ocsillating too? How do you muse? P.S. If some net charge acceleration occurs upon the bondong process, then do you think that some electromagnetic radition accompanies?

Hello! I am the lab technician at an industrial metal producing plant where I test it's anodic coating on the metal. One of my main components of my job is to titrate and monitor concentration of the tank line. I can perform one color titration because I did them in college. However, there's a test that involves two titrations in one flask. The person before me left months ago, so I wasn't able to get proper training other other than a lady who hasn't taken a science course in her life. So folks, I have questions about the double titration. Procedures: 5mL sample, 50mL water, 4 drops methyl orange, 4 drops phenalphalein(sp) Experiment: Find the concentration of sulfuric acid and aluminum in a 4500 gallon tank. Calculations: A * 9.8 = concentration of sulfuric acid g/L B * 1.8 = concentration of aluminum g/L With what I know in an acid-base titration, the color changes when it reaches the equivalence point. When I titrate I see many phases of color. Red to orange to bright orange to slight red, then full red. Where are the equivalence point to solve for A and B? I am getting several results.

Nowadays, computational methods are routinely used to accelerate drug discovery process. In drug design and discovery, multiple computational chemistry approaches are employed to calculate and predict events, such as the drug binding to its target and the chemical properties for designing potential new drugs. I'm currently doing a project that would incorporate computational techniques into drug design, and would like to know if any other opinions here.
