Question

Люди, помогите разобраться 1) KNO2 + KMnO4 + H2O 2) K2SO3 + KMnO4 + H2SO4 ОВР

Answer 1

1) 

2K+¹Mn+⁷O-²₄ + 3K+¹N+³O-²₂ + H+¹2O-² = 3K+¹N+⁵O-²₃ + 2Mn+⁴O-²₂ + 2K+¹O-²H+¹

   

Mn+⁷ + 3e- = Mn+⁴ I 6 I 2 I окисл.; вос.

N+³ - 2e- = N+⁵       I 6 I 3 I вос.; окисл..

2)

5K2SO3 + 3H2SO4 + 2KMnO4 → 6K2SO4 + 2MnSO4 + 3H2O

S+4 - 2e → S+6 окисление,
Mn+7 + 5e → Mn+2 восстановление. 

5 S+4 - 2e → S+6
2 Mn+7 + 5e→ Mn+2 

. 

Answer 2

1) KNO2 + KMnO4 + H2O: - The chemical equation you provided consists of three compounds: KNO2, KMnO4, and H2O. - KNO2 is the chemical formula for potassium nitrite. - KMnO4 is the chemical formula for potassium permanganate. - H2O is the chemical formula for water. - When these compounds react, they undergo a chemical reaction, resulting in the formation of new compounds or products. - To determine the specific reaction and products, we need more information about the conditions and stoichiometry of the reaction.

2) K2SO3 + KMnO4 + H2SO4: - The chemical equation you provided consists of three compounds: K2SO3, KMnO4, and H2SO4. - K2SO3 is the chemical formula for potassium sulfite. - KMnO4 is the chemical formula for potassium permanganate. - H2SO4 is the chemical formula for sulfuric acid. - When these compounds react, they undergo a chemical reaction, resulting in the formation of new compounds or products. - To determine the specific reaction and products, we need more information about the conditions and stoichiometry of the reaction.
