Laughing gas is the common name for nitrous oxide, which has the chemical formula \(N_2O\). It is a colorless, non-flammable gas with a slightly sweet odor and taste. Nitrous oxide is used in medicine as an anesthetic and analgesic, as well as in the food industry as a propellant for whipped cream. When inhaled, it can induce feelings of euphoria and laughter, hence the name "laughing gas".
