Solution: Chlorine gas was first prepared in 1774 by C. W. Scheele by oxidizing sodium chloride with manganese(IV) oxide. The reaction isNaCl (aq) + H2SO4 (aq) + MnO2 (s) → Na 2SO4 (aq) + MnCl 2 (aq) + H2O (l)

Problem

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

NaCl (aq) + H2SO4 (aq) + MnO2 (s) → Na 2SO4 (aq) + MnCl 2 (aq) + H2O (l) + Cl 2 (g)

Balance this equation.
