Question

do you know NOx gas? where will be used?!!!​

Answer 1

Explanation:

In atmospheric chemistry, NO

x is a generic term for the nitrogen oxides that are most relevant for air pollution, namely nitric oxide (NO) and nitrogen dioxide (NO

2).[1][2] These gases contribute to the formation of smog and acid rain, as well as affecting tropospheric ozone.

NO

x gases are usually produced from the reaction among nitrogen and oxygen during combustion of fuels, such as hydrocarbons, in air; especially at high temperatures, such as in car engines.[1][2][3] In areas of high motor vehicle traffic, such as in large cities, the nitrogen oxides emitted can be a significant source of air pollution. NO

x gases are also produced naturally by lightning.
