The structure of this salt was verified by X-ray crystallography. The respective C–O and C–N distances are 1.174(8) and 1.192(7) Å , consistent with the O=C=N − description. Ammonium cation [NH 4 ] + forms hydrogen bonds with cyanate anion O=C=N − , but to N, not to O. [ 1 ]
Ammonium cyanide decomposes to ammonia and hydrogen cyanide, often forming a black polymer of hydrogen cyanide: [1] NH 4 CN → NH 3 + HCN. It undergoes salt metathesis reaction in solution with a number of metal salts to form metal–cyanide complexes.
A notable molecule editor is a computer program for creating and modifying representations of chemical structures.. Molecule editors can manipulate chemical structure representations in either a simulated two-dimensional space or three-dimensional space, via 2D computer graphics or 3D computer graphics, respectively.
Wavy single bonds represent unknown or unspecified stereochemistry or a mixture of isomers. For example, the adjacent diagram shows the fructose molecule with a wavy bond to the HOCH 2 - group at the left. In this case the two possible ring structures are in chemical equilibrium with each other and also with the open-chain structure.
A Nassi–Shneiderman diagram (NSD) in computer programming is a graphical design representation for structured programming. [1] This type of diagram was developed in 1972 by Isaac Nassi and Ben Shneiderman who were both graduate students at Stony Brook University. [2] These diagrams are also called structograms, [3] as they show a program's ...
It is a rare example of a soluble platinum(IV) salt that is not hygroscopic. It forms intensely yellow solutions in water. It forms intensely yellow solutions in water. In the presence of 1M NH 4 Cl , its solubility is only 0.0028 g/100 mL.
Ammonium thiocyanate is used in the manufacture of herbicides, thiourea, and transparent artificial resins; in matches; as a stabilizing agent in photography; in various rustproofing compositions; as an adjuvant in textile dyeing and printing; as a tracer in oil fields; in the separation of hafnium from zirconium (important for the production of hafnium-free zircalloy for use in nuclear fuel ...
Most nitrolic acids are laboratory curiosities. One exception is the compound HO 2 C(CH 2) 4 C(NO 2)=NOH, which is produced by the oxidation of cyclohexanone with nitric acid. [3] This species decomposes to adipic acid and nitrous oxide: HO 2 C(CH 2) 4 C(NO 2)=NOH → HO 2 C(CH 2) 4 CO 2 H + N 2 O
