Can you provide some redox reactions practice problems for me to work on?

Here are some redox reaction practice problems for you to work on:

1. Balance the following redox reaction: Fe CuSO4 - FeSO4 Cu
2. Identify the oxidizing agent and reducing agent in the reaction: 2K Cl2 - 2KCl
3. Determine the oxidation state of sulfur in H2SO4
4. Balance the following redox reaction in acidic solution: MnO4- H2C2O4 - Mn2 CO2
5. Calculate the change in oxidation state for sulfur in the reaction: H2S Cl2 - S HCl

Good luck with your practice!
