# Write down the molecular and ionic equations for the exchange of barium chloride with each

**Write down the molecular and ionic equations for the exchange of barium chloride with each of the indicated substances: a) sulfuric acid; b) sodium sulfate; c) calcium sulfate**

Let us write down the equation for the reaction between barium chloride and sulfuric acid.

BaCl2 + H2SO4 = BaSO4 + HCl

Let’s arrange the coefficients:

BaCl2 + H2SO4 = BaSO4 + 2HCl

Let us write down the complete and abbreviated reaction equations.

Ba ^ (2+) + 2Cl ^ (-) + 2H ^ (+) + SO4 ^ (2-) = BaSO4 + 2H ^ (+) + 2Cl ^ (-)

Ba ^ (2+) + SO4 ^ (2-) = BaSO4

Let us write the reaction equation for the interaction of barium chloride and sodium sulfate.

BaCl2 + Na2SO4 = BaSO4 + NaCl

Let’s arrange the coefficients:

BaCl2 + Na2SO4 = BaSO4 + 2NaCl

Let us write down the complete and abbreviated reaction equations.

Ba ^ (2+) + 2Cl ^ (-) + 2Na ^ (+) + SO4 ^ (2-) = BaSO4 + 2Na ^ (+) + 2Cl ^ (-)

Ba ^ (2+) + SO4 ^ (2-) = BaSO4

Let us write down the reaction equation for the interaction of barium chloride and calcium sulfate.

BaCl2 + CaSO4 = BaSO4 + CaCl2

Let us write down the complete and abbreviated reaction equations.

Ba ^ (2+) + 2Cl ^ (-) + Ca ^ (2+) + SO4 ^ (2-) = BaSO4 + Ca ^ (2+) + 2Cl ^ (-)

Ba ^ (2+) + SO4 ^ (2-) = BaSO4
