2. Carbon monoxide - Wikipedia

   en.wikipedia.org/wiki/Carbon_monoxide

   Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...

3. Ottoman (furniture) - Wikipedia

   en.wikipedia.org/wiki/Ottoman_(furniture)

   An ottoman is a piece of furniture. [1] Generally, ottomans have neither backs nor arms. They may be an upholstered low couch or a smaller cushioned seat used as a table, stool or footstool. The seat may have hinges and a lid for the inside hollow, which can be used for storing linen, magazines, or other items, making it a form of storage ...

4. Dicobalt octacarbonyl - Wikipedia

   en.wikipedia.org/wiki/Dicobalt_octacarbonyl

   The preparation is often carried out in the presence of cyanide, converting the cobalt(II) salt into a pentacyanocobaltate(II) complex that reacts with carbon monoxide to yield K[Co(CO) 4]. Acidification produces cobalt tetracarbonyl hydride, HCo(CO) 4, which degrades near room temperature to dicobalt octacarbonyl and hydrogen.

5. Carbonyl sulfide - Wikipedia

   en.wikipedia.org/wiki/Carbonyl_sulfide

   Carbonyl sulfide was first described in 1841, [21] but was apparently mischaracterized as a mixture of carbon dioxide and hydrogen sulfide. Carl von Than first characterized the substance in 1867. It forms when carbon monoxide reacts with molten sulfur: CO + ⁠ 1 / 8 ⁠ S 8 → COS. This reaction reverses above 1200 K (930 °C; 1700 °F).

6. Mond process - Wikipedia

   en.wikipedia.org/wiki/Mond_process

   This process involves the fact that carbon monoxide combines with nickel readily and reversibly to give nickel carbonyl. No other element forms a carbonyl compound under the mild conditions used in the process. [2] This process has three steps: 1. Nickel oxide reacts with syngas at 200 °C to give nickel, together with impurities including iron ...

7. Boudouard reaction - Wikipedia

   en.wikipedia.org/wiki/Boudouard_reaction

   It is the disproportionation of carbon monoxide into carbon dioxide and graphite or its reverse: [1] 2CO ⇌ CO 2 + C Boudouard-Equilibrium at 1 bar calculated with 2 different methods Standard enthalpy of the Boudouard reaction at various temperatures. The Boudouard reaction to form carbon dioxide and carbon is exothermic at all
