Hydrothermal vents and the origins of life - Chemistry World
WEBApr 16, 2017 — In 1977, the first deep sea hydrothermal vent was discovered in the East Pacific Rise mid-oceanic ridge. Named ‘black smokers’, the vents emit geothermally heated water up to 400°C, with high levels of sulfides that precipitate on contact with the cold ocean to form the black smoke. This was followed in 2000 by the discovery of a new type ...
Explainer: Why is mixing cleaning chemicals such a bad idea?
WEBApr 23, 2020 — Chlorine gas is toxic, forms acids on contact with wet surfaces, such as home plumbing but also living tissue, such as the lungs. Heating or contact with metals can also cause bleach to decompose via a different route. 2NaOCl → O 2 + 2NaCl. Mixing hypochlorite with ammonia would see the breakdown of the hypochlorite to generate hypochlorous ...

History of noble gases | Feature | Chemistry World
WEBSep 9, 2016 — Pushing the limits. Ramsay retired in 1912, but his love of hands-on experimental work, which was the key to his success, was also fatal. No precautions were taken in handling the radioactive material; radium was even put into cosmetics and pharmaceuticals, and Ramsay’s notebook from that period is still radioactive.

WEBDec 21, 2016 — The men farted between two and 53 times a day, with an average of 12.7, while women farted between once and 32 times a day, with an average of 7.1 times. The number of farts was higher when people ate more fibre. The study shows farting is normal, Stanton says. ‘I hope that has translated to people …
The father of the periodic table | Feature | Chemistry World
WEBJan 2, 2019 — A century and a half ago, Dmitri Mendeleev took a crucial step in this search for order among the elements, by publishing the first draft of his periodic table. In 2019 the world-wide community of chemists is celebrating this anniversary, and rightly so. Like Stonehenge, the table reflects regularities in nature which were due to causes that ...
Explainer: The science of alkyl nitrites aka poppers
WEBSep 16, 2021 — Inhaling alkyl nitrites feels like becoming instantly drunk according to some users, although the effect lasts for only a few minutes. Also known as poppers, these chemicals have been taken recreationally since the 1960s. Although they are sold openly, usually in small brown bottles with enticing brand names such as ‘liquid gold’, their ...
What is an element? | Feature | Chemistry World
WEBJan 10, 2019 — Iupac currently gives a double definition of ‘element’ in its ‘Gold Book’ of chemical terminology, which says that the word can refer either to a ‘species of atom’ (which Ghibaudi sees as akin to Paneth’s ‘basic substance’) or, rather tautologically, to a ‘pure elementary substance’. This double meaning is uncomfortable.
