Final answer:
Dysprosium oxide reacts with hydrochloric acid to produce dysprosium chloride and water. Dysprosium chloride is the salt formed in this chemical reaction.
Step-by-step explanation:
The reaction between dysprosium oxide, Dy₂O₃, and hydrochloric acid produces water and a salt. The salt formed in this reaction is dysprosium chloride, DyCl₃. This occurs as the oxide reacts with the acid to release water molecules and form the corresponding chloride salt of dysprosium.
Considering a balanced equation for the reaction:
Dy₂O₃(s) + 6HCl(aq) → 2DyCl₃(aq) + 3H₂O(l)
This shows that dysprosium oxide reacts with hydrochloric acid to yield dysprosium chloride and water as the only products.
