Question

what is the chemical name for n₂o₃?
nitrogen trioxide
dinitrogen trioxide
pentanitrogenoxide
nitrogen oxide

Explanation:

When naming covalent compounds, the prefixes indicate the number of atoms. For \(N_2O_3\), there are 2 nitrogen (\(N\)) atoms. The prefix for 2 is "di -", so it's "dinitrogen". There are 3 oxygen (\(O\)) atoms. The prefix for 3 is "tri -", and the root of oxygen is "ox" with the ending "-ide", so it's "trioxide". Combining these, the name is dinitrogen trioxide.

Answer:

dinitrogen trioxide
