Explanation:

Step1: Analyze the prefixes

In chemical nomenclature, "di - " means 2 and "tri - " means 3. For dinitrogen trisulfide, "di - " is for nitrogen (\(N\)) and "tri - " is for sulfur (\(S\)).

Step2: Write the formula

Based on the prefixes, the formula should have 2 nitrogen atoms and 3 sulfur atoms. So the formula is \(N_2S_3\).

Answer:

\(N_2S_3\) (the third option)
