Pellets of "dry ice", a common form of solid carbon dioxide. Carbon dioxide is colorless. At low concentrations, the gas is odorless; however, at sufficiently high concentrations, it has a sharp, acidic odor. [1] At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m 3, about 1.53 times that of air. [27]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
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.
There are many oxides of carbon , of which the most common are carbon dioxide (CO 2) and carbon monoxide (CO). Other less known oxides include carbon suboxide (C 3 O 2 ) and mellitic anhydride (C 12 O 9 ). [ 5 ]
Carbon dioxide is written CO 2; sulfur tetrafluoride is written SF 4. A few compounds, however, have common names that prevail. H 2 O, for example, is usually termed water rather than dihydrogen monoxide, and NH 3 is preferentially termed ammonia rather than nitrogen trihydride.
Dry ice is the solid form of carbon dioxide (CO 2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, odorless, and non-flammable, and can lower the pH of a solution when dissolved in water , forming carbonic acid (H 2 CO 3 ).
Liquid carbon dioxide is the liquid state of carbon dioxide (CO 2 ), which cannot occur under atmospheric pressure. It can only exist at a pressure above 5.1 atm (5.2 bar; 75 psi), under 31.1 °C (88.0 °F) (temperature of critical point ) and above −56.6 °C (−69.9 °F) (temperature of triple point ). [ 1 ]
The other common oxide is carbon monoxide (CO). It is formed by incomplete combustion, and is a colorless, odorless gas. ... (his name for carbon dioxide) ...
