i. A balanced chemical equation has the same number of moles of reactants and products.The balanced chemical equation is: \[BaCl_{2(aq)} + Na_2SO_{4(aq)} \rightarrow BaSO_{4(s)} + 2NaCl_{(aq)}\]
ii. A balanced chemical equation has the same number of moles of reactants and products. The balanced chemical equation is: \[NaOH_{(aq)}+HCl_{(aq)} \rightarrow NaCl_{(aq)}+H_2O_{(l)}\]
