Nitrous oxide physical properties

Nitrous oxide is a moderately unreactive gas comprised of linear unsymmetrical molecules, as expected for a 16-electron triatomic species (p. 433). The symmetrical structure N-O-N is precluded on the basis of orbital energetics. Some physical properties are in Table 11.8 it will be seen that the N-N and N-O distances are...

Nitrous oxide (N20) was first prepared by Priestly in 1772. Its anaesthetic properties were described by Sir Humphrey Davy in 1800 and it was first used in clinical practice by Colton and Wells in 1844. Physical characteristics... 

A. 0. Rankine found that the mols. of nitrous oxide and carbon dioxide behave physically as if they had the same size, shape, and electronic structure. I. Langmuir compared the physical properties of carbon dioxide and of nitrous oxide, and the similarity was attributed to a like electronic structure—vide 4. 27, 4, Fig. 30. G. Kirsch made observations on the electronic structure of the molecule and M. L. Huggins made estimates of the interatomic distances.

With nitrous oxide at 200° C. ferrous oxide is produced.4 Nitrogen is absorbed by the heated metal to a slight extent, particularly when melted under a high pressure of the gas, yielding the nitride.5 The nitride is also produced by heating the metal to 800° C. m an atmosphere of ammonia, the physical properties of the metal undergoing considerable alteration. 

A gas supply and pump or flow regulator usually make up the source when a GC-like set-up is being used. The most common mobile phase for SFC is carbon dioxide this is based on its low cost, low interference with chromatographic detectors and good physical properties. Other examples include nitrous oxide and ammonia. Supercritical fluids can... 

The first hint that a physical property of a drug could be related to biological activity appeared almost 100 years ago when scientists recognized that chloroform (CHCI3), diethyl ether, cyclopropane, and nitrous oxide (N2O) were all useful general anesthetics. Clearly, the chemical stmctures of these diverse compounds could not account for their similar pharmacological effects. Instead, some physical property must explain the similarity of their biological activities. 

Common names are arbitrary names that are not based on the chemical composition of compounds. Before chemistry was systematized, a substance was given a name that generally associated it with one of its outstanding physical or chemical properties. For example, quicksilver is a common name for mercury, and nitrous oxide (N2O), used as an anesthetic in dentistry, has been called laughing gas because it induces laughter when inhaled. Water and ammonia are also common names because neither provides any information about the chemical composition of the compounds. If every substance were assigned a common name, the amount of memorization required to learn over 12 million names would be astronomical.

Non-flammable compressed gases do not catch fire easily or bum quickly. However, they possess other hazards. The cylinder label and SDS will tell you about the toxic properties and physical hazards. Ammonia, argon, carbon dioxide, nitrogen, oxygen, chlorine, and nitrous oxide are all non-flammable compressed gases. These gases may ...
