Answer 2

The balanced chemical equation for the reaction between hydrogen sulfide (H2S) and iron(III) oxide (Fe2O3) is:

3H2S + Fe2O3 → 2FeS + 3S + 3H2O

To determine the electron transfer that occurs during the reaction, we need to look at the oxidation states of the atoms involved.

In H2S, hydrogen has an oxidation state of +1 and sulfur has an oxidation state of -2.

In Fe2O3, iron has an oxidation state of +3 and oxygen has an oxidation state of -2.

In FeS, iron has an oxidation state of +2 and sulfur has an oxidation state of -2.

The oxidation state of sulfur changes from -2 to 0, which means it gains two electrons. This occurs in both FeS and S.

The oxidation state of iron changes from +3 to +2, which means it gains one electron. This occurs in FeS.

Therefore, the electron transfer that occurs during the reaction is:

3H2S + Fe2O3 → 2FeS + 3S + 3H2O

Sulfur gains two electrons, and iron gains one electron.
