Make the equation: 1, sodium sulfate + barium nitrate 2, calcium carbonate + hydrochloric acid 3, potassium hydroxide + copper sulfate 2 4, iron hydroxide 3 + sulfuric acid
1) Sodium sulfate + barium nitrate: Ba (No3) 2 + Na2So4 = BaSo4 + 2NaNo3.
2) Calcium carbonate + hydrochloric acid: CaCO3 + 2HCl = CaCl2 + CO2 + H2O.
3) Potassium hydroxide + copper sulfate: СuSO4 + 2KOH = K2SO4 + Cu (OH) 2.
4) Iron (III) hydroxide + sulfuric acid: 3H2SO4 + 2Fe (OH) 3 = 6H2O + Fe2 (SO4) 3.
