(b) The top shows both the dot-and-cross diagram and the simplified diagram of the LDQ structure of the NO radical. Below is shown the dimerisation reaction of the NO monomer into the N 2 O 2 dimer. Hence, the dimerisation of CN to cyanogen is favourable as it increases the degree of bonding in the overall system and reduces the total energy.

CuCl 2 reacts with HCl or other chloride sources to form complex ions: the red [CuCl 3] − (found in potassium trichloridocuprate(II) K[CuCl 3]) (it is a dimer in reality, [Cu 2 Cl 6] 2−, a couple of tetrahedrons that share an edge), and the green or yellow [CuCl 4] 2− (found in potassium tetrachloridocuprate(II) K 2 [CuCl 4]).
Simplified diagram of the Copper–Chlorine cycle. The copper–chlorine cycle (Cu–Cl cycle) is a four-step thermochemical cycle for the production of hydrogen. The Cu–Cl cycle is a hybrid process that employs both thermochemical and electrolysis steps. It has a maximum temperature requirement of about 530 degrees Celsius. [1]
Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
The crystal structure of the dihydrate was partially determined in 1927 by Hendricks and Dickinson [1] [4] and refined in 1934 by Chrobak. [5] The structure is tetragonal P4 2 /mnm (136), Z=2, isostructural with ammonium tetrachoridocuprate(II) (NH 4) 2 CuCl 4 ·2 H 2 O and rubidium tetrachoridocuprate(II) Rb 2 CuCl 4 ·2 H 2 O.
The same hydrochloric acid solutions also react with acetylene gas to form [CuCl(C 2 H 2)]. Ammoniacal solutions of CuCl react with acetylenes to form the explosive copper(I) acetylide, Cu 2 C 2. Alkene complexes of CuCl can be prepared by reduction of CuCl 2 by sulfur dioxide in the presence of the alkene in alcohol solution.
