Question

what is the formula of this binary molecular compound? dinitrogen pentoxide n₂o ni₂o₅ n₂o₅ n(ii)o(v)

Explanation:

Step1: Analyze the prefixes

The prefix "di -" means 2, so there are 2 nitrogen atoms. The prefix "penta -" means 5, so there are 5 oxygen atoms.

Step2: Write the formula

Based on the number of atoms from the prefixes, the formula is \(N_2O_5\).

Answer:

\(N_2O_5\) (the third option in the given choices)
