Answer:
molecular eq.
Cs2SO4 (aq) + BaBr2(aq) → BaSO4(s) + 2CsBr(aq)
ionic eq.
SO₄²-(aq) + Ba^+2 (aq) → BaSO4 (s)
explanation
separate the ions
Cs₂^+1(aq) + SO₄^+2(aq) + Ba^+2(aq) + Br₂^-1(aq) → BaSO₄(s) + 2Cs(aq) + Br(aq)
than simplify it
SO₄²-(aq) + Ba^+2 (aq) → BaSO4 (s)
Llowing certain substances to pass through it but not others, especially allowing the passage of a solvent but not of certain solutes.
