What is the balanced, net ionic equation for the reaction shown below: Ba(NO3)2(aq) + Na2SO4(aq) → 2 NaNO3(aq) + BaSO4(s)
Question 16 options:

Ba2+(aq) + SO2−4(aq) → BaSO4(s)

Ba2+(aq) + 2 NO−3(aq) + 2 Na+(aq) + SO2−4(aq) → 2 Na+(aq) + 2 NO−3(aq) + BaSO4(s)

Ba2+(aq) + 2 NO−3(aq) + 2 Na+(aq) + SO2−4(aq) → 2 Na+(aq) + 2 NO−3(aq) + Ba2+(aq) + SO2−4(aq)

2 NO−3(aq) + 2 Na+(aq) → 2 NaNO3(s)
