Nitrous oxide transfer of nitrous oxide from bulk cylinders to smaller, more transportable E-type, 1590 liter-capacity tanks, is legal when the intended use of the gas is for medical anaesthesia. Nitrous oxide Nitrous oxide, commonly known as laughing gas or nitrous, is a chemical compound, an oxide of nitrogen with the formula . At room temperature, it is a colourless non-flammable gas, with a slight metallic scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen. It is soluble in water. Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and
Dihydrogen complex agostic interaction that is displaced by the H. In other cases, H will displace anionic ligands, sometimes even halides. Treatment of chlorobis(dppe)iron hydride with sodium tetrafluorborate under and atmostphere of hydrogen is one example: Many metal hydrides can be protonated to give dihydrogen complexes: In such cases the acid usually is derived from a weakly coordinating anion, e.g., Brookhart's acid. In 1984, Kubas et al. discovered that the addition of H to the purple-colored species M(CO)(PR) gave a yellow precipitate of mer-trans-M(CO)(PR)(H) (M = Mo or W; R = cyclohexyl, iso-propyl). This result rapidly led to the discovery of a
