One day in lab, while taking apart a complicated distillation apparatus, your friend Dan (an expert chemist) says this: "Metal sulfides react with strong acids to produce hydrogen sulfide and a salt." Using Dan's statement, and what you already know about chemistry, predict the products of the following reaction. Be sure your chemical equation is balanced! Fe $3(s) + HNO3(aq) → I 0-0
