One day in lab, while taking apart a complicated distillation apparatus, your friend Debra (an expert chemist) says this:
"Metal sulfides react with strong acids to produce hydrogen sulfide and a salt."
Using Debra's statement, and what you already know about chemistry, predict the products of the following reaction.
Be sure your chemical equation is balanced!
Fe2S3 (s) + HCl (aq)
Based on Debra's statement, we can predict that Fe2S3 will react with HCl to produce hydrogen sulfide (H2S) and a salt (an iron chloride).
The balanced chemical equation for this reaction would be:
Fe2S3 (s) + 6 HCl (aq) → 2 FeCl3 (aq) + 3 H2S (g)
