Answer #1

AU MnO2 (s) + i - mn?t tel. MnO2 Mn2t : MnO2 - mn2+ + 2H2O MnO2 + 4H+ + 2é z mnlt + 2H20 - 0. 201 the C2+ z é . . Adding & . method of balancing

1) first balance atoms except O and H

2) balance O by adding water to minimum side

3) balance H by adding H+ to minimum side

4) balance charges by adding electrons

5) in basic medium, after balancing H by H+, add the same number OH- ions to both sides.
