Final answer:
The IUPAC name for Ag3O is silver(I) oxide. Silver has a +1 oxidation state in this compound, similar to its state in silver chloride (AgCl). The correct answer is options C.
Step-by-step explanation:
The name for the compound Ag3O in systematic chemical nomenclature according to the International Union of Pure and Applied Chemistry (IUPAC) is silver(I) oxide. In this compound, silver has a +1 oxidation state. We can deduce this oxidation state from related compounds with known charges, such as silver chloride (AgCl). In AgCl, silver also has a +1 oxidation state, as chlorine has a -1 charge.
By combining three silver ions (Ag+) with one oxygen ion (O2-), which has a charge of -2, it neutralizes the charge: 3(Ag+) + (O2-) = Ag3O, resulting in no overall charge for the compound. Thus, silver oxide is the correct IUPAC name for Ag3O, making option (c) the answer.
