The discovery of krypton occurred partially by accident.
Scottish chemist William Ramsay and English chemist Morris Travers were extracting argon for air in hopes of evaporating it and finding a lighter chemical element to fill the gap in the Periodic Table between argon and helium.
You’re either new to the sport of cycling or you’ve been riding for a few years, learning the ropes on an old aluminum frame that’s one season away from the dumpster.
You’ve been watching all the Spring classics, the Giro, the Vuelta, and the Tour taking notes on who’s riding what.
He then added additional oxygen until all the nitrogen had reacted. Cavendish used aqueous sodium hydroxide to remove them from the apparatus.
[This would also, of course, have removed any carbon dioxide that was present.] He removed the remaining oxygen using potassium polysulfides. Cavendish wrote that this bubble “was not more than one hundred and twentieth of the bulk of the phlostigated air [nitrogen].” So, Cavendish is saying that air is at least 99.3 percent nitrogen/oxygen/carbon dioxide with a maximum 0.7 percent of something else.
Don’t take it wrong, carbon indeed has its merits, but the recent carbon craze seems to be heavily tied to bandwagon mentality; whatever the pros are doing is what the masses want to do too.
It was true in the ‘70s with drilled-out components, in the ‘80s with copious amounts of hair gel and Briko shades, in the ‘90s with those horrific lycra shorts designed to look like blue jeans, and today with carbon racing bikes. A frame and fork weighs less than a six-pack of brew, they’ve got terrific road damping capabilities, are stiffer than an I-beam – at least initially – and most importantly, carbon fiber has an indisputable cool factor.
The gas is injected into some incandescent lightbulbs, because it extends the life of the tungsten filament that makes those bulbs glow, according to Universal Industrial Gases Inc., a supplier of industrial gases production equipment and related services.
More than ten million compounds of carbon are known.
No other element, except for hydrogen, occurs in even a fraction of that number of compounds.
William Ramsay discovered argon when he first saw its spectrum and realized it matched no other’s. Cavendish was unhappy that so little was known about air.
He was particularly unhappy about the lack of information about the fraction of air (the majority) which was not oxygen.
