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 the
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
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 at
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
