$"Barium hydroxide + lithium sulfate "rarr" barium sulfate + lithium hydroxide"$

$Ba(OH)_2(aq) + Li_2SO_4(aq) rarr BaSO_4(s)darr + Li(OH)_2(aq)$

$Ba^(2+) + cancel(2HO^(-)) + cancel(2Li^+) + SO_4^(2-) rarr BaSO_4(s)darr +cancel(2Li^+) + cancel(2HO^(-))$

And net, because hydroxide and lithium ions are simply along for the ride:

$Ba^(2+) + SO_4^(2-) rarr BaSO_4(s)darr$

Is mass conserved? Is charge conserved in each equation? If not, they should be!
