Carbonyl fluoride is usually produced as a decomposition product of fluorinated hydrocarbons in the thermal decomposition thereof, for example from trifluoromethanol or tetrafluoromethane in the presence of water:
Anhydrous cobalt(II) fluoride. Cobalt(II) fluoride is a chemical compound with the formula (CoF 2).It is a pink crystalline solid compound [1] [2] which is antiferromagnetic at low temperatures (T N =37.7 K) [3] The formula is given for both the red tetragonal crystal, (CoF 2), and the tetrahydrate red orthogonal crystal, (CoF 2 ·4H 2 O).
Vitamin B12 is a cobalt-centered organic biomolecule, soluble in water, and involved in the methylation and synthesis of nucleic acid and neurotransmitter. [20] The main source is the offal or meat of herbivorous animals. [21] Dicobalt octacarbonyl (Co 2 (CO) 8) is an orange-red crystal with two isomers in solution: [22]
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Robert Angus Smith FRS (15 February 1817 – 12 May 1884), commonly referred to as Angus Smith, [1] was a Scottish chemist, who investigated numerous environmental issues.He is known for his research on air pollution in 1852, in the course of which he discovered what came to be known as acid rain.
Where an acid has both a systematic and a common name (like CH 3 COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name. Thus, KCH 3 CO 2 can be named as potassium acetate or as potassium ethanoate.
The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
