What is the chemical name for the compound represented by N2O5?

The compound N2O5 is composed of two nitrogen atoms and five oxygen atoms. In chemical nomenclature, the prefixes are used to indicate the number of each type of atom present in the formula. The prefix "di-" denotes two, and "penta-" denotes five.

Thus, when naming the compound N2O5, we recognize there are two nitrogen atoms, which leads to "dinitrogen," and five oxygen atoms, resulting in "pentoxide." Combining these gives us the full name "dinitrogen pentoxide."

This nomenclature follows the convention for covalent compounds, where prefixes are essential in denoting the quantity of each element. The correct identification and application of these prefixes result in naming the compound accurately as dinitrogen pentoxide.
