C. mononitrogen dioksida 5. Pemberian nama senyawa biner N_(2)O_(3) dengan memakai angka Romawi yang ini adalah __ A. nitrogen (I) oksida D (IV) oksida B. nitrogen (II) oksida E. nitrogen (V) oksida C. nitrogen (III) oksida

The correct answer is **C. nitrogen (III) oxide**. Here's why:* **Naming Binary Compounds:** Binary compounds are made up of two elements. When naming them, we use prefixes to indicate the number of each element present.* **Prefixes:** * Mono - 1 * Di - 2 * Tri - 3 * Tetra - 4 * Penta - 5* **Roman Numerals:** We use Roman numerals to indicate the oxidation state (charge) of the metal in the compound.**Let's break down the compound N₂O₃:*** **Nitrogen (N):** The nitrogen atoms have a total oxidation state of +6 (2 x +3).* **Oxygen (O):** The oxygen atoms have a total oxidation state of -6 (3 x -2).Since the compound is neutral, the oxidation states must balance. Therefore, each nitrogen atom has an oxidation state of +3.**Therefore, the correct name for N₂O₃ is nitrogen (III) oxide.**
