Nitrous Oxide

1.) Chemical compound N(2 subscript)O, which consists of two nitrogen atoms to one oxygen atom. 2.) Form of performance enhancer for automobiles, used to introduce extra air into cylinders by causing an chemical reaction that decomposes the N20 into Oxygen and Nitrogen. This increases pressure inside the cylinders, which ultimately results in a horsepower increase. 3.) Used in dentist's offices for numbing during oral surgeries, known as Laughing Gas.
