Answer 1

We have done several of these for you before. Look them over. You should be able to handle this. I'll do an abbreviated response and you should be able to follow it.

NO₃^- ==> NO₂

NO₃^- +2H⁺ + e-==> NO₂ + H₂O [x2] = 2NO₃^- +4H⁺ + 2-==> 2NO₂ + 2H₂O

H₂O₂ ==> O₂ + 2H⁺ + 2e-

2NO₃^- + 2H⁺ + H₂O₂ ==> 2NO₂ + O₂ + 2H₂O ... BALANCED REDOX EQUATION

BrO₃^- ==> Br^-

BrO₃^- +6H⁺ +6e- ==> Br^- + 3H₂O

Fe²⁺ ==> Fe³⁺ + e- [x6] = 6Fe²⁺ ==> 6Fe³⁺

BrO₃^- + 6Fe²⁺ + 6H⁺ ==> Br^- + 6Fe³⁺ + 3H₂O ... BALANCED REDOX EQUATION
