The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
Changing a wheel on a Lockheed P-3 Orion aircraft Tires on the wheels of a bogie on a Boeing 777. An aircraft tire or tyre is designed to withstand extremely heavy loads for short durations. [1] The number of tires required for aircraft increases with the weight of the aircraft, as the weight of the airplane needs to be distributed more evenly.

Nitrogen compounds have a very long history, ammonium chloride having been known to Herodotus. They were well-known by the Middle Ages. They were well-known by the Middle Ages. Alchemists knew nitric acid as aqua fortis (strong water), as well as other nitrogen compounds such as ammonium salts and nitrate salts.
Many other binary nitrogen hydrides are known, but the most important are hydrazine (N 2 H 4) and hydrogen azide (HN 3). Although it is not a nitrogen hydride, hydroxylamine (NH 2 OH) is similar in properties and structure to ammonia and hydrazine as well. Hydrazine is a fuming, colourless liquid that smells similarly to ammonia.
The name of the chemical element Nitrogen is also a cognate to natron, it derives from Greek nitron and -gen (a producer of something, in this case Nitric acid, which was produced from niter (potassium nitrate)). Niter was also an obsolete name for natron because in earlier times, both minerals used to be confused with each other.
It is a potassium salt of nitric acid. This salt consists of potassium cations K + and nitrate anions NO − 3, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [5] It is a source of nitrogen, and nitrogen was named after niter.
Airless tires are attractive to cyclists, as bicycle tires are much more vulnerable to punctures than motor vehicle tires. The drawbacks to airless tires depend on the use. Heavy equipment operators who use machinery with solid tires may become fatigued. Any airless tire will be heavier than the rubber tire it is meant to replace.
