Final answer:
The compound Sn(SO3)2 is named tin(IV) sulfite, indicating that the tin is in a +4 oxidation state and is combined with two sulfite anions.
Step-by-step explanation:
The compound named Sn(SO3)2 consists of tin (Sn) and the anion SO32-, which is named sulfite. Given that tin can have multiple positive oxidation states, we use a Roman numeral in parentheses to indicate the charge of the tin cation. In this case, since SO3 has a 2- charge and there are two of them, the tin must have a +4 charge to balance the charges and make the compound neutral. Therefore, the correct name for Sn(SO3)2 is tin(IV) sulfite.
