Textbook Problem

Chlorine gas was first prepared in 1774 by C. W. Scheele by oxidizing sodium chloride with manganese(IV) oxide. The reaction is

$\text{NaCl}(aq)+{\text{H}}_{\text{2}}{\text{SO}}_4(aq)+{\text{MnO}}_{\text{2}}(s)\to {\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}(aq)+{\text{MnCl}}_{\text{2}}(aq)+{\text{H}}_{\text{2}}\text{O}(l)+{\text{Cl}}_{\text{2}}(g)$

Balance this equation.
