(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.

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]
2 CuCl 2 → 2 CuCl + Cl 2 The reported melting point of copper(II) chloride of 498 °C (928 °F) is a melt of a mixture of copper(I) chloride and copper(II) chloride. The true melting point of 630 °C (1,166 °F) can be extrapolated by using the melting points of the mixtures of CuCl and CuCl 2 .
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.

Peters four-step chemistry is a systematically reduced mechanism for methane combustion, named after Norbert Peters, who derived it in 1985. [1] [2] [3] The mechanism reads as [4]
