Let's correct and complete the chemical reactions:<br /><br />a) $H_{2}SO_{4} + Mg = MgSO_{4} + H_{2}$<br />b) $H_{2}SO_{4} + BaCl_{2} = BaSO_{4} + 2HCl$<br />c) $H_{2}SO_{4} + Zn = ZnSO_{4} + H_{2}$<br />d) $H_{2}SO_{4} + K_{2}S = K_{2}SO_{4} + H_{2}S$<br />e) $SO_{3} + K_{2}O = K_{2}SO_{4}$<br />f) $SO_{2} + Na_{2}O = Na_{2}SO_{3}$<br /><br />These are the balanced chemical equations for the given reactants.
