What are the half reactions of the formulas below? Also which half reaction is oxidized and what is reduced?
- Al + Fe2O3 -> Al2O3 + Fe
- NH3 + O2 -> NO + H2O
- H2 + F2 -> HF
- Cu + AgNO3 -> Cu (NO3)2 + Ag
- Fe + ZnCl2 -> FeCl3 + Zn
- Al + Fe -> AlF3
- S + Cl2 -> SCL6
- Co + Fe2O3 -> Fe + Co2
- Al + Fe (NO3)2 -> Al (NO3)3 +Fe
- Cr^3+ + ClO3 -> CRO4^2- + Cl-
