A group of hikers encountering quicksand on the banks of the Paria River, Utah Quicksand warning sign near Lower King Bridge, Western Australia. Quicksand is a shear thinning non-Newtonian fluid: when undisturbed, it often appears to be solid ("gel" form), but a less than 1% change in the stress on the quicksand will cause a sudden decrease in its viscosity ("sol" form).
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 ...
Carbon monoxide (CO) is a colorless, practically odorless, and tasteless gas or liquid. ... Carbon monoxide exposure can lead to flu-like symptoms that disappear once you leave the affected area ...
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]
Normally, carbon is tetravalent, while oxygen is divalent, and in most oxocarbons (as in most other carbon compounds) each carbon atom may be bound to four other atoms, while oxygen may be bound to at most two. Moreover, while carbon can connect to other carbons to form arbitrarily large chains or networks, chains of three or more oxygens are ...
Carbon monoxide is particularly dangerous because it is colourless and odourless, making it impossible to detect without the necessary equipment. Symptoms of carbon monoxide poisoning may include ...
Relative to carbon monoxide and hydrogen sulfide, NO is exceptional due to the fact it is a radical gas. [28] NO is highly reactive (having a lifetime of a few seconds), yet diffuses freely across membranes. These attributes make NO ideal for a transient paracrine (between adjacent cells) and autocrine (within a single cell) signaling molecule.
In the conversion of carbon dioxide to useful materials, the water–gas shift reaction is used to produce carbon monoxide from hydrogen and carbon dioxide. This is sometimes called the reverse water–gas shift reaction. [19] Water gas is defined as a fuel gas consisting mainly of carbon monoxide (CO) and hydrogen (H 2).
