Consider the reaction between dissolved Fe²* and elemental sulfur (S°) to form hematite (Fe2O3) and sulfide HS- Fe2+ + S° → Fe2O3 + HS- a) Identify the oxidant and reductant in this reaction, determine half-reactions, and balance the reaction. b) Is this reaction thermodynamically favorable? c) Would you expect HS to react readily with Fe2O3 (i.e. the reverse of the reaction)?
