Nitrous oxide, also called nitrous oxide, is a colorless and sweet gas. It is an oxidant with the chemical formula N2O, which can support combustion under certain conditions (like oxygen, because nitrous oxide can be decomposed into nitrogen and oxygen at high temperature), but it is stable at room temperature, has a slight anesthetic effect and can make people laugh.

Nitrous oxide molecules have a linear structure. One nitrogen atom is connected to another nitrogen atom, and the second nitrogen atom is connected to an oxygen atom. It can be considered as a resonant mixture of sum.

history

Nitrous oxide was discovered by joseph priestley in 1772. humphry davy himself and his friends, including poets Coleridge and robert southey, experimented with this gas in the 1990s. They found that nitrous oxide can make patients lose their pain, and they can still remain conscious after inhalation and will not be unconscious.

Nitrous oxide was soon used as an anesthetic, especially in the field of dentistry. Because dentists usually don't have full-time anesthesiologists, patients often need to stay awake and make oral reactions according to the doctor's advice during the diagnosis and treatment. gas here brings great convenience to dentists.
