<reasoning>

Identify the elements and subscripts

\[
\text{Formula: } \text{N}_2\text{O}_5
\]
\[
\text{Elements: Nitrogen (N), Oxygen (O)}
\]
\[
\text{Subscripts: 2 for Nitrogen, 5 for Oxygen}
\]

Apply covalent naming prefixes

\[
\text{Prefix for 2: di-}
ightarrow \text{dinitrogen}
\]
\[
\text{Prefix for 5: penta-}
ightarrow \text{pentoxide}
\]

Combine the terms

\[
\text{Name: dinitrogen pentoxide}
\]
