Question

Help me!!! AgNO3=Ag+NO2+O2 KMnO4+K2SO3+H2O=MnO2+K2SO4+KOH

Answer 1

1)2AgNO3=2Ag+2NO2+O2.
Ag[+]+e=Ag[0]|2-окислитель
N[+5]+e=N[+4]|2-окислитель
O[-2]-2e=O[0]|1-восстановитель.
2)2KMnO4+3K2SO3+H2O=2MnO2+3K2SO4+2KOH.
Mn[+7]+3e=Mn[+4]|2-окислитель
S[+4]-2e=S[+6]|3-восстановитель.

Answer 2

Chemical Equation:

The chemical equation you provided is: AgNO3 = Ag + NO2 + O2 + KMnO4 + K2SO3 + H2O = MnO2 + K2SO4 + KOH.

Balancing the Equation:

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's balance it step by step:

1. Balancing the first reaction: AgNO3 = Ag + NO2 + O2 - The number of Ag atoms is already balanced. - The number of N atoms is already balanced. - The number of O atoms is not balanced. There are 3 O atoms on the left side and 2 O atoms on the right side. To balance it, we need to add another O2 molecule on the right side. - The balanced equation is: AgNO3 = Ag + NO2 + O2.

2. Balancing the second reaction: KMnO4 + K2SO3 + H2O = MnO2 + K2SO4 + KOH - The number of K atoms is not balanced. There are 3 K atoms on the left side and 4 K atoms on the right side. To balance it, we need to add another K2SO4 molecule on the left side. - The number of Mn atoms is not balanced. There is 1 Mn atom on the left side and 1 Mn atom on the right side. The MnO2 molecule on the right side already contains 1 Mn atom, so it is balanced. - The number of O atoms is not balanced. There are 4 O atoms on the left side and 2 O atoms on the right side. To balance it, we need to add another H2O molecule on the right side. - The number of S atoms is not balanced. There is 1 S atom on the left side and 1 S atom on the right side. The K2SO4 molecule on the right side already contains 1 S atom, so it is balanced. - The number of H atoms is not balanced. There are 2 H atoms on the left side and 2 H atoms on the right side. The KOH molecule on the right side already contains 2 H atoms, so it is balanced. - The balanced equation is: KMnO4 + K2SO3 + H2O = MnO2 + K2SO4 + KOH.

Therefore, the balanced chemical equation is: AgNO3 = Ag + NO2 + O2 + KMnO4 + K2SO4 + KOH = MnO2 + K2SO4 + KOH.
