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 .
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). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel , cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron .
Carbon dioxide is a chemical compound with the chemical formula CO 2. It is made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature and at normally-encountered concentrations it is odorless.
Carbon trioxide (CO 3) is an unstable oxide of carbon (an oxocarbon). The possible isomers of carbon trioxide include ones with molecular symmetry point groups C s , D 3h , and C 2v . The C 2v state, consisting of a dioxirane , has been shown to be the ground state of the molecule. [ 1 ]
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Dicarbon monoxide is a product of the photolysis of carbon suboxide: [2] [3]. C 3 O 2 → CO + C 2 O. It is stable enough to observe reactions with NO and NO 2. [4]Called ketenylidene in organometallic chemistry, it is a ligand observed in metal carbonyl clusters, e.g. [OC 2 Co 3 (CO) 9] +.
