Question

Помогите ПЛИЗ(определить конечные продукты реакции, уравнять методом электронного баланса.Cl2+ HNO2 →.K2SeO3 + Br2 + KOH →

Answer 1

HNO2 + Cl2 + H2O = HNO3 + 2HCl.
N(+3)-2e=N(+5)  ок-е вос-ль
Cl2(0)+2e=2Cl(-)  вос-е ок-ль

 K2SeO3+ Br2+ 2KOH = K2SeO4+ 2КBr+ Н2О
Se(+4)-2e=Se(+6)  ок-е вос-ль
Br2(0)+2e=2Br(-)    вос-е ок-ль

Answer 2

Determining the Reaction Products and Balancing the Equation

To determine the final products of the reaction and balance the equation, we can follow these steps:

1. Write the unbalanced equation: Cl2 + HNO2 → K2SeO3 + Br2 + KOH

2. Determine the oxidation states of each element in the reaction.

3. Balance the atoms and charges in the half-reactions.

4. Combine the half-reactions and simplify if necessary.

Let's proceed with these steps to determine the final products and balance the given chemical equation.

Step 1: Write the Unbalanced Equation

The unbalanced chemical equation provided is: Cl2 + HNO2 → K2SeO3 + Br2 + KOH

Step 2: Determine the Oxidation States

To balance the equation, we first need to determine the oxidation states of the elements involved in the reaction.
