Many general chemistry textbooks introduced the concept "hybridization" to construct a symmetry-adapted VB-type wavefunction. In the textbooks, usually the minimal basis is used and without optimizing all resonance forms. My question is, in the ab initio valence bond calculation with extended ba...

Standard protocols report the selective deprotection of primary silyl ethers in the presence of secondary silyl ethers under acidic conditions, as exemplary shown in scheme 1, a reaction by Hartmann and Kalesse.[1] Scheme 1: Selective deprotection of a primary silyl ether[1] Numerous other exa...

I have a solution of copper(II) ions and several cations. I am trying to reduce the copper ions to copper metal with electricity. My Ideas was to use silver as the anode and a copper wire as the cathode. I have seen people say to do this using platinum as the anode, however this is expensive. ...

The Peng-Robinson equation of state, for example, has no underlying physical meaning, and is just a model that was fit to data. Computer scientists have developed much, much better models for data than messing around with polynomials and exponentials, like neural networks. Why can't standards org...

This is the same question that I asked before, only for another product this time. I have more detailed information about this product, including a data sheet. There is an 8000 liter tank containing water for household use like showers and washing dishes and clothes (but not drinking or cooking)...
