Answer 1

Hi i am showing one process how to balance the redox reactions in acidic medium, please do other the same way it is very hard work for me to type and upload here.

Alternatively if you know programming as i do with python, C+, C++ make a script i always do that and my research done like that way.

Part A:

3IO₃^- (aq) + 2MnO₄^- (aq) + 2H⁺ (aq) → 3IO₄^- (aq) + 2MnO₂ (s) + H₂O (l)

Part B:

N₂H₄ (aq) + 2Cu(OH)₂ (s) → N₂ (g) + 2Cu (s) + 4H₂O (l)

Part C:

3Fe(OH)₂ (s) + CrO₄^2- (aq) + 3H₂O (l) + H⁺ (aq) → 3Fe(OH)₃ (s) + Cr(OH)₄^- (aq)

Part D:

2H₂O₂ (aq) + ClO₄^- (aq) → 2O₂ (g) + ClO₂^- (aq) + 2H₂O (l)
