At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by-product of petroleum refining. Its chief use is as feedstock for ethylene production. The ethyl group is formally, although rarely practically, derived from ethane.
Radon is a colorless, odorless, and tasteless [15] gas and therefore is not detectable by human senses alone. At standard temperature and pressure , it forms a monatomic gas with a density of 9.73 kg/m 3 , about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m 3 . [ 16 ]
The excimers used for lasers may be noble gas dimers such as Ar 2, Kr 2 or Xe 2, or more commonly, the noble gas is combined with a halogen in excimers such as ArF, KrF, XeF, or XeCl. These lasers produce ultraviolet light, which, due to its short wavelength (193 nm for ArF and 248 nm for KrF), allows for high-precision imaging.
It's odorless, colorless and deadly. And now, carbon monoxide is yet again in the news. Multiple news outlets report the gas has been preliminarily blamed for the deaths of a dozen people who ...
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
Propane is a colorless, odorless gas. Ethyl mercaptan is added as a safety precaution as an odorant , [ 23 ] and is commonly called a "rotten egg" smell. [ 24 ] At normal pressure it liquifies below its boiling point at −42 °C and solidifies below its melting point at −187.7 °C.
Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon atom. Isobutane is used as a precursor molecule in the petrochemical industry , for example in the synthesis of isooctane .
It is a dense, colorless, odorless noble gas found in Earth's atmosphere in trace amounts. [17] Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate , the first noble gas compound to be synthesized.
