Make the equation of the reaction resulting in the following salts: 1) barium sulfate 2) barium nitrate 3) sodium sulfate.

There are many options for obtaining the listed salts, then one of them is proposed:
1) Interaction of barium hydroxide with sulfuric acid to form water-insoluble barium sulfate and water:
Ba (OH) 2 + H2SO4 = BaSO4 + 2H2O
2) Interaction of barium hydroxide with nitric acid with the formation of barium nitrate and water:
Ba (OH) 2 + 2HNO3 = Ba (NO3) 2 + 2H2O
3) Interaction of sodium silicate with sulfuric acid to form sodium sulfate and water-insoluble silicic acid:
Na2SiO3 + H2SO4 = Na2SO4 + H2SiO3
