Hope Trachsel Hour:1 LAUGHING GAS Chemical Name: Nitric oxide Chemical Formula: N2O Common Name: laughing gas Formula Weight: 44 Common Uses: It is a weak anesthetic (painkilling) gas - used in dental surgery - used in the dairy industry because it helps bacteria from growing - used in cars for speed combustion History of the Compound: The gas was first mad by and English philosopher and chemist named Joseph Priestley in 1772, he called it phlogisticated nitrous air. He described how to produce the preparation of the gas by heating iron filings dampened with nitric acid in the book Experiments and Observations of Different Kinds of Air. Dentist, Horace Wells was the first to give a patient this anesthetic drug. Room Temperature: it is a colorless non-flammable gas, with a slightly sweet odor and taste. Model of the compound: Video of a little girl on laughing gas: http://www.youtube.com/watch?v=h9oa24Pn77E&playnext=1&list=PL42228D998F3CD 1DD&index=14 Physical Properties: 1. Molecular weight: 44.02 2. Boiling point (at 760 mm Hg): -88.5 degrees C (-127.3 degrees F) 3. Specific gravity (air = 1): 1.97 at 25 degrees C (77 degrees F) 4. Vapor density: 1.53 5. Melting point: -91 degrees C (-132 degrees F) 6. Vapor pressure: 760 mm Hg at 88.5 degrees C (191.3 degrees F) 7. Solubility: Slightly soluble in water; soluble in alcohol, ether, oils, and sulfuric acid . How is it made?: It is made by the thermal decomposition of ammonium nirtate. Here is a picture of what they use to make it in: How much does it cost?: Anywhere from $50- $500 Is is poisonous?: NO Type of Chemical Bond: Covalent Bond Interesting Facts: - Anyone who possesses nitrous oxide and is under the influence of it is guilty of a misdemeanor - Dangers of this gas can be tripping, falling over something and hurting yourself or if you take in too much you can die. - It increases blood flow to the muscles which in turn helps to deliver and transport blood and nutrients more adequately to these muscles Sources: http://www.justsayn2o.com/ This website gave interesting facts about this gas and you'd go here to learn about how it can be helpful and dangerous chemical. http://www.nitrousdirect.com/nitrousoxide.html This website contained the physical and chemical properties of the chemical.
