Nitrous Oxide Gas N2O

Nitrous oxide is a colorless and odorless anesthetic gas with a slightly sweet taste at normal temperature and pressure, also called nitrous oxide, commonly known as laughing gas. It does not burn in the air, but it can support combustion. Inhalation of large amounts of nitrous oxide can cause anesthesia and suffocation.
