Question

KOH+Br2=KBr+KBrO+H2Oпомогите срочно ОВР

Answer 1

           0      -1      +1
2KOH+Br2=KBr+KBrO+H2O

 окислитель           Br2(0)+2е--> 2Br(-1)  восстановление
 восстановитель   Br2(0)-2е--> 2Br (+1) окисление

это реакция диспропорционирования, процесс самоокисление и самовосстановление 
Br2 является и окислителем и восстановителем за счет Br(0)

Answer 2

6KOH + Br2 = KBrO3 + 5KBr +3 H2O

Br2(0)-10e=2Br(+5)|1восстановитель
Br2(0)+2e = 2Br(-)|5 окислитель

(степени окисления(пишешь над елементами над 1 уравнением)
KOH ( K(+)O(-2)H(+))
Br2 (0)
KBrO3 (К +1 )(Br +5 )(O -2)
KBr (K+1)(Br-1)
H2O (h+1)(o-2) 

Answer 3

Chemical Equation Balancing

The chemical equation provided is: KOH + Br2 = KBr + KBrO + H2O. This equation represents the reaction between potassium hydroxide and bromine.

To balance this chemical equation, we can follow these steps: 1. Count the atoms of each element on both sides of the equation. 2. Adjust the coefficients to balance the number of atoms for each element.

Balancing the given chemical equation: Step 1: Count the atoms of each element on both sides of the equation. - Potassium (K): 1 K on the left, 1 K in KBr, and 1 K in KBrO, so the K is already balanced. - Oxygen (O): 1 O in KOH and 1 O in H2O on the left, 1 O in KBrO on the right, so the O is already balanced. - Hydrogen (H): 1 H in KOH and 2 H in H2O on the left, so the H is not balanced. - Bromine (Br): 1 Br in Br2 on the left, 1 Br in KBr and 1 Br in KBrO on the right, so the Br is not balanced.

Step 2: Adjust the coefficients to balance the number of atoms for each element. The balanced chemical equation is: 2 KOH + Br2 = 2 KBr + KBrO + H2O

This balanced equation ensures that the number of atoms for each element is the same on both sides of the equation.
