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 :)
