Answer 2

A) Ba(OH)2 + HCl → BaCl2 + 2H2O Molecular: Barium hydroxide + Hydrochloric acid → Barium chloride + Water Ionic (complete): Ba(OH)2(aq) + 2H+(aq) + 2Cl-(aq) → Ba2+(aq) + 2Cl-(aq) + 2H2O(l) Ionic (net): Ba(OH)2(aq) + 2H+(aq) → Ba2+(aq) + 2H2O(l)

б) K2S + H2SO4 → 2KHS + K2SO4 Molecular: Potassium sulfide + Sulfuric acid → Potassium bisulfide + Potassium sulfate Ionic (complete): 2K+(aq) + S2-(aq) + 2H+(aq) + SO42-(aq) → 2K+(aq) + HSO4-(aq) + K2SO4(aq) Ionic (net): S2-(aq) + 2H+(aq) → HSO4-(aq)

в) BaCl2 + MgSO4 → BaSO4 + MgCl2 Molecular: Barium chloride + Magnesium sulfate → Barium sulfate + Magnesium chloride Ionic (complete): Ba2+(aq) + 2Cl-(aq) + Mg2+(aq) + SO42-(aq) → BaSO4(s) + Mg2+(aq) + 2Cl-(aq) Ionic (net): Ba2+(aq) + SO42-(aq) → BaSO4(s)

г) FeCl2 + 2NaOH → Fe(OH)2 + 2NaCl Molecular: Iron(II) chloride + Sodium hydroxide → Iron(II) hydroxide + Sodium chloride Ionic (complete): Fe2+(aq) + 2Cl-(aq) + 2Na+(aq) + 2OH-(aq) → Fe(OH)2(s) + 2Na+(aq) + 2Cl-(aq) Ionic (net): Fe2+(aq) + 2OH-(aq) → Fe(OH)2(s)
