Question

Complete and balance the following reactions:

(1) NaCl + MnO₂ + H₂SO₄ → _____ + _____ + ______ + _____

(2) KMnO₄ + SO₂ + H₂O → _____ + ______ + ______ + ______

Answer 1

\[\begin{array}{cc}
\ce{\phantom{...}\delta+ \phantom{...}\delta-\phantom{..}\phantom{..}\delta+ \phantom{..}\delta- \phantom{...}\delta+ \phantom{..}\delta- \phantom{..} \phantom{.}\delta^{-1}\phantom{...}\delta-}\phantom{..}\\
\ce{--H--O--H--O--H--O--H--O--}\\
\phantom{......}\backslash\phantom{..........} \backslash \phantom{..........}\backslash \phantom{.........}\backslash\phantom{}\\
\phantom{.............}\ce{H^{\delta+}\phantom{.......}H^{\delta+}\phantom{........}H^{\delta+}\phantom{......}H^{\delta+}\phantom{...}}
\end{array}\]

(1) \[\ce{2NaCL +MnO2 +3H2SO4 -> 2NaHSO4 +MnSO4 +2H2O+CI2}\]

(2) \[\ce{2KMnO4 + 5SO2 +2H2O ->K2SO4 + 2MnSO4 +2H2SO4 }\]
