Nitric oxide is produced during thunderstorms due to the extreme heating and cooling within a lightning strike. This causes stable molecules such as N2 and O2 to convert into significant amounts of NO similar to the process that occurs during high temperature fuel combustion. NOx from lightning can become oxidized to produce nitric acid (HNO3), this can be precipitated out as acid rain or deposited onto particles in the air. Elevated production of NOx from lightning depend… WebNitrogen oxides are released to the air from the exhaust of motor vehicles, the burning of coal, oil, or natural gas, and during processes such as arc welding, electroplating, engraving, and dynamite blasting. They are also produced commercially by reacting nitric acid with metals or cellulose.
WebJan 25, 2024 · How is nitrogen oxide prepared? Ans: Nitrogen oxides are produced during combustion by the reaction of nitrogen and oxygen gases in the air, particularly at high temperatures. Oxygen and nitrogen gases do not react together at room temperature. A lightning strike naturally produces nitrogen oxides.
