2.
Write the balanced equation for "Barium chloride + Aluminium sulphate → Barium sulphate + Aluminium chloride".
\(3BaCl_2\) +\(Al_2(SO_3)_3\) → \(3BuSO_4\) + \(2AlCl_3\)
\(3BaCl_2\) +\(Al_2(SO_4)_3\) → \(3BaSO_4\) + \(2AlCl_3\)
\(3BaCl_2\) +\(Al_2(SO_3)_3\) → \(3BeSO_4\) + \(2AlCl_3\)
\(3BuCl_2\) +\(Al_2(SO_3)_3\) → \(3BeSO_4\) + \(2AlCl_3\)
