Make equations: Hydrochloric acid and barium oxide, Sodium sulfide and nitric acid, Potassium oxide and hydrobromic acid, Sodium sulfate and hydrochloric acid, Copper sulfate and hydrofluoric acid, Sulfuric acid and iron oxide (2)
Decision:
1.hydrochloric acid and barium oxide: BaO + 2HCl = BaCl2 + H2O
2.sodium sulfide and nitric acid: Na2S + 2HNO3 = 2NaNO3 + H2S
3.potassium oxide and hydrobromic acid: K2O + 2HBr = 2KBr + H2O
4. sodium sulfate and hydrochloric acid, as well as copper sulfate and hydrofluoric acid, will not interact with each other, because there is a rule that if salt and acid react, the acid must be stronger than that in the salt.
5.sulfuric acid and iron oxide (2): H2SO4 + FeO = FeSO4 + H2O
