Unfortunately, Dr.Bob didn't answer the question. It is generally true (not always), but elements close to each other on the periodic chart, like O and N, particularly non-metals form molecular compounds. Moreover, the question is tricky. In the gas phase...

HF is a weak acid, so you need the dissociation constant. The pH at the equivalence point is found by calculating the pH of a 0.4M NaF solution (a hydrolysis problem). If you erroneously assume that HF is a strong acid, then the answer is simple. The pH a...

The NH3 doesn't replace the Cl-. AgCl is not very soluble. The AgCl that does dissolve solvates with water forming in solution Ag(H2O)2+ and Cl-. (the 2 is a subscript) The NH3 coordinates more strongly than water, so the NH3 replaces the coordinated wate...

An orbit is a specific path an electron follows around the nucleus of an atom. It is an obsolete idea that comes from the Bohr (bohring) model of hydrogen. A much more interesting model comes from quantum mechanics. It considers a region a space around th...
