1. Balance the following chemical equation.

\(BaCl_2\) + \(H_2SO_4\) → \(BaSO_4\) + \(HCl\)

\(BaCl_2\) + \(H_2SO_4\) → \(BaSO_4\) + \(3HCl\)
\(BaCl_2\) + \(H_2SO_4\) → \(BaSO_4\) + \(2HCl\)
\(BaCl_2\) + \(HSO_4\) → \(BaSO_4\) + \(2HCl\)
\(BaCl_2\) + \(H_3SO_4\) → \(BaSO_4\) + \(HCl\)
\(BaCl_2\) + \(H_2SO_4\) → \(BaSO_8\) + \(2HCl\)

2. Write the balanced chemical equations for the following reactions.

Barium chloride + Potassium sulphate → Barium sulphate + Potassium chloride

\(BaCl_2\) + \(K_3SO_4\) → \(BaSO_4\) + \(2KCl\)
\(BaCl_2\) + \(K_2SO_4\) → \(BaSO_4\) + \(KCl\)
\(BaCl_3\) + \(K_2SO_4\) → \(BaSO_4\) + \(2KCl\)
\(BeCl_2\) + \(K_2SO_4\) → \(BaSO_4\) + \(2KCl\)
\(BaCl_2\) + \(K_2SO_4\) → \(BaSO_4\) + \(2KCl\)
