The compound's name is iron (III) oxide.

Explanation:

Fe is Iron. We see that S has the subscript of "3", and the two elements make up an ionic compound. So we know that electrons were transferred. Thus we can determine that it was Iron (III).

Fe has a subscript of 2. Reversing the transfer, we get sulfur's charge.

Therefore, the compound's name is iron (III) oxide.

Hope this helps :)
