NO n2o is right!!!
Nitrous oxide, commonly known as "laughing gas", is a chemical compound with the chemical formula N2O.

yea but look again, cause the nitrous oxide your refering to as laughing gas; thats used in dentistry. the nitrous oxide we use on the street is a totaly different animal. n2o is for the dentist, and no2 is for the racers
 
Yup, it is definately N20, but don't think you can inhale this laughing gas. Sulfur is added to non-medical nitrous to prevent you from attempting that.
