# What is the name of Fe_2S_3?

Jan 30, 2017

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

#### Explanation:

$F e$ 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).

$F e$ 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 :)
