explain how nitrogen oxides are produced and their environmental impact.

Let's explore how nitrogen oxides (NOx) are produced and what their environmental impacts are. Nitrogen oxides mainly include nitric oxide (NO) and nitrogen dioxide (NO₂), gases formed primarily during combustion processes when nitrogen and oxygen react at high temperatures. Before we dive into details, can you share how familiar you are with combustion and air pollution topics? For example, have you studied anything about vehicle emissions, or is this a new topic for you?
