Final answer:
The correct formula for dinitrogen trioxide is N₂O₃, which consists of two nitrogen atoms and three oxygen atoms.
Step-by-step explanation:
The correct formula for dinitrogen trioxide is c. N₂O₃.
Dinitrogen trioxide is named by the prefixes 'di-' and 'tri-' to indicate the number of nitrogen and oxygen atoms respectively. The chemical compound contains two nitrogen atoms and three oxygen atoms. In accordance with the rules for naming inorganic compounds, nitrogen is named first because it is located to the left of oxygen on the periodic table. Oxygen gets the suffix '-ide' as it is the second element named in the formula. It is important to note that as with other inorganic compounds, the prefixes used in the name are directly reflected in the chemical formula.
