What is the correct answer to balance the electrons
OX: Zn ZnO
RED: 2 MnO, + Mn,0,
1. Find the half reactions
OX: Zn ZnO
RED: 2 Mno, Mn,O,
2. Balance atoms except O and H
OX: H,O+ Zn ZnO
RED: 2 Mno, Mn,O,+ H,O
3. Balance O by adding H2O
4. Balance H by adding H*
OX: H,O + Zn Zno + 2 H
RED: 2 Mno, + 2 HMn,O,+ H,0
5. Balance charges by adding e-
