Ammonium chloride is an inorganic chemical compound with the chemical formula N H 4 Cl, also written as [NH 4]Cl.It is an ammonium salt of hydrogen chloride.It consists of ammonium cations [NH 4] + and chloride anions Cl −.
Lewis structure of a water molecule. Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule.
The structure of the inorganic chloropolymer product (Poly(dichlorophosphazene)) comprises a linear – (N=P(−Cl) 2 −) n chain, where n ~ 15000. [ 2 ] [ 4 ] It was first observed in the late 19th century and its form after chain cross-linking has been called "inorganic rubber" due to its elastomeric behaviour.
The electronic structure of a coordination complex can be described in terms of the set of ligands each donating a pair of electrons to a metal centre. For example, in hexamminecobalt(III) chloride, each ammonia ligand donates its lone pair of electrons to the cobalt(III) ion. In this case, the bonds formed are described as coordinate bonds.

How Cialis Works. Cialis is a prescription medication designed to treat ED. It’s approved for this use by the U.S. Food and Drug Administration (FDA). Tadalafil is the active ingredient in Cialis.
In the biological system, the counterions would more probably be Mg 2+, but the heavy atoms of cobalt (or sometimes iridium, as in ) provide anomalous scattering to solve the phase problem and produce an electron-density map of the structure. [6] [Co(NH 3) 6] 3+ is used to investigate DNA. The cation induces the transition of DNA structure from ...
