What does the chemical symbol NoX mean?

The chemical symbol NoX typically refers to nitrogen oxides, which are a group of gases that include nitric oxide (NO) and nitrogen dioxide (NO2). These compounds are primarily produced from combustion processes and are significant pollutants that contribute to air quality issues and the formation of smog. The "X" in NoX indicates that it can represent more than one nitrogen oxide species.


How do you calculate nox in ambient air?

NOx in ambient air is typically measured using a chemiluminescence method. This technique involves chemically reacting NO and NO2 with ozone to produce light, which is then measured to quantify the concentration of NOx. Other methods include using gas analyzers or employing passive samplers to collect NOx for later analysis in a laboratory.


What are three products of respireation?

Gases(co2, Nox etc), water and heat


Are NOx gases greenhouse gases?

Yes, NOx gases are considered greenhouse gases. They contribute to global warming by trapping heat in the Earth's atmosphere. Additionally, they play a role in the formation of smog and acid rain.


Explain what would happen to CO2 and nox if the co levels were high?

High CO levels can increase the formation of nitrogen oxides (NOx) through reactions with nitrogen in the atmosphere. This leads to increased NOx levels in the air. However, if CO concentrations are high enough, the combustion process in engines can be inefficient, leading to incomplete combustion and higher CO emissions.
