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.
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 .
The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. [34] They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds .
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]
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 ...
Carbon monoxide is an odorless and colorless gas that can build up in enclosed or partially enclosed spaces, poisoning people and animals who breathe in too much, according to the CDC. The gas can ...
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 .
Colorless, odorless gas spewing from the tanker at State Route 128 and U.S. Route 50 was reported to first responders shortly after 1 p.m., Chief Mike Siefke of the Little Miami Joint Fire and ...
