Chemical Burning

Chemical burns are the result of very normal reactions that can occur between the offending material and living tissue components. People generally tend to regard their bodies as things outside of the ... Continue reading

Exploding Fertilizer

Atmospheric nitrogen is a diatomic molecule of just two nitrogen atoms bonded very strongly to each other. Nitrogen, in compound with other elements, is just a single nitrogen atom bonded very weakly, ... Continue reading

Crops benefit from nitrogen-based fertilizers as in this field of safflower, Carthamus tinctorius L.

What Give Batteries Their Charge?

There is in chemistry only one function that is of fundamental importance: the ability of atoms to share electrons. In any such sharing program, there must be electron donors and electron acceptors. ... Continue reading

Knocking the NOx Out of Coal

Nitrogen is the most common part of the air we breathe. In fact, about 80% of the air is nitrogen. Normally, nitrogen atoms float around joined to each other like chemical couples. But when air is ... Continue reading

Air is mostly nitrogen molecules (green in the above diagram) and oxygen molecules (purple). When heated hot enough (around 3000 degrees F), the molecules break apart and oxygen atoms link with the nitrogen atoms to form NOx, an air pollutant.
