The main product of bacterial action is_________________?
Correct answer: D. NO
- A. Nox
- B. NO2
- C. N2O3
- D. NO
Explanation
In bacterial nitrogen transformations, nitric oxide, NO, can be produced as an intermediate during reduction of nitrogen oxides. Students may choose NO2 because it is the more familiar atmospheric nitrogen oxide, but bacterial action in this context is associated with NO formation.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
