CoBr 2 ·6H 2 O → CoBr 2 ·2H 2 O + 4 H 2 O. Further heating to 130 °C produces the anhydrous form: CoBr 2 ·2H 2 O → CoBr 2 + 2 H 2 O. The anhydrous form melts at 678 °C. [2] [3] At higher temperatures, cobalt(II) bromide reacts with oxygen, forming cobalt(II,III) oxide and bromine vapor. The tetrahydrate is molecular, with the formula ...
Cobalt(II) azide (Co(N 3) 2) is another binary compound of cobalt and nitrogen that can explode when heated. Cobalt(II) and azide can form Co(N 3) 2− 4 complexes. [9] Cobalt pentazolide Co(N 5) 2 was discovered in 2017, and it exists in the form of the hydrate [Co(H 2 O) 4 (N 5) 2]·4H 2 O. It decomposes at 50~145 °C to form cobalt(II) azide ...
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
For example, (CH 3) 2 CHCH 3, commonly known as isobutane, is treated as a propane chain with a methyl group bonded to the middle (2) carbon, and given the systematic name 2-methylpropane. However, although the name 2-methylpropane could be used, it is easier and more logical to call it simply methylpropane – the methyl group could not ...
cis-Dichlorobis(ethylenediamine)cobalt(III) chloride is a salt with the formula [CoCl 2 (en) 2]Cl (en = ethylenediamine). The salt consists of a cationic coordination complex and a chloride anion. It is a violet diamagnetic solid that is soluble in water.
3 COOH, which is commonly called acetic acid and is also its recommended IUPAC name, but its formal, systematic IUPAC name is ethanoic acid. The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [1] [2] and the Red Book, [3] respectively.
118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Carbonyl bromide, also known as bromophosgene, is a carbon oxohalide and a bromine analogue of phosgene, with the chemical formula COBr 2. It is a colorless liquid. It is a colorless liquid. Carbonyl bromide is a decomposition product of halon compounds used in fire extinguishers .
