Here's the balanced chemical equation for the reaction between barium nitrate (Ba(NO₃)₂) and lithium sulfate (Li₂SO₄):

Ba(NO₃)₂ (aq) + Li₂SO₄ (aq) → BaSO₄ (s) + 2LiNO₃ (aq)

Explanation:

* Reactants:

* Barium nitrate (Ba(NO₃)₂) is dissolved in water (aq)

* Lithium sulfate (Li₂SO₄) is dissolved in water (aq)

* Products:

* Barium sulfate (BaSO₄) is a white solid (s) that precipitates out of solution.

* Lithium nitrate (LiNO₃) remains dissolved in the solution (aq).

* Balancing: The equation is balanced by ensuring that the number of atoms of each element is the same on both sides of the equation.
