NxOy

NxOy is a chemical notation used to describe a specific type of compound. It is read as "nutoxys" or simply "nutoxi," however it is a protected trademark by the Japanese company Mitsubishi Chemicals and the term might be used interchangeably for describing a specific class of nitrogen oxides, but often refers to a single compound.

In general, chemical notation represents a compound containing nitrogen and oxygen, with the prefix "N" indicating the presence of nitrogen and "O" indicating the presence of oxygen. The suffix "x" or "y" indicates the variable number of oxygen atoms.

One of the most well-known compounds described by the notation NxOy is nitrogen dioxide, also known as NO2. It is a reddish-brown gas with a unpleasant odor, commonly linked to environmental pollution. It is often released from combustion sources such as buses, generators and industrial plants.

While the notation NxOy is general, some specific compounds have been identified by using this notation. However, some compounds described with the notation may be misused or inaccurately represented. The notation might be confused with the nitrogen oxides, or just to be used for a variable chemical composition, so context is necessary to understand the meaning of the term.

Studies and further analysis of the NxOy compounds continues, including efforts to identify the essential responses of common nitrogen oxides in variable environmental conditions.
