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 .
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
A model of the carbon monoxide molecule. A monoxide is any oxide containing only one atom of oxygen. A well known monoxide is carbon monoxide; see carbon monoxide poisoning. The prefix mono (Greek for "one") is used in chemical nomenclature. [1] In proper nomenclature, the prefix is not always used in compounds with one oxygen atom. [2]
Carbon monoxide is a dangerous and silent killer. The colorless and odorless toxic gas kills hundreds of people every year and sickens thousands more, according to the U.S. Centers for Disease ...
In chemistry, an oxocarbon or oxide of carbon is a chemical compound consisting only of carbon and oxygen. [1] [2] The simplest and most common oxocarbons are carbon monoxide (CO) and carbon dioxide (CO 2).
Air gas consists principally of carbon monoxide with nitrogen from the air used and a small amount of hydrogen. This term is not commonly used, and tends to be used synonymously with wood gas. Producer gas: Air gas modified by simultaneous injection of water or steam to maintain a constant temperature and obtain a higher heat content gas by ...
Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. [3] Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion. [1] Large exposures can result in loss of consciousness, arrhythmias, seizures, or death.
Since the heat of combustion of these elements is known, the heating value can be calculated using Dulong's Formula: HHV [kJ/g]= 33.87m C + 122.3(m H - m O ÷ 8) + 9.4m S where m C , m H , m O , m N , and m S are the contents of carbon, hydrogen, oxygen, nitrogen, and sulfur on any (wet, dry or ash free) basis, respectively.
