he mineral rhodochrosite [manganese(II) carbonate, MnCO3] is a commercially important source of manganese. Write a half-reaction
valina [46]

Answer:

MnCO_{3}+2H_{2}O-2e^{-}\rightarrow MnO_{2}+HCO_{3}^{-}+3H^{+}

Explanation:

Half reaction:MnCO_{3}\rightarrow MnO_{2}

(1)CO_{3} balance: MnCO_{3}\rightarrow MnO_{2}+HCO_{3}^{-}

(2)H and O balance in acidic medium:MnCO_{3}+2H_{2}O\rightarrow MnO_{2}+HCO_{3}^{-}+3H^{+}

(3) charge balance:MnCO_{3}+2H_{2}O-2e^{-}\rightarrow MnO_{2}+HCO_{3}^{-}+3H^{+}

Hence balanced half-reaction:MnCO_{3}+2H_{2}O-2e^{-}\rightarrow MnO_{2}+HCO_{3}^{-}+3H^{+}
