Question

Напишите уравнения реакций,с помощью которых можно осуществить следующие превращенияHNO3---Cu(NO3)2---NO2---HNO3---NH4NO3---NH3---NO

Answer 1

Cu + 4HNO3(конц.) = Cu(NO3)2 + 2NO2 + 2H2O

Cu(NO3)2 (прокаливание) = CuO + 2NO2 + O2

 4NO2+2H2O+O2=4HNO3

HNO3 + NH3 = NH4NO3

NH4NO3 + KOH = NH3 + H2O + KNO3

4NH3 + 5O2 = 4NO + 6H2O

 

 

 

 

 

 

Answer 2

Equations for the Given Transformations

To achieve the transformations from HNO3 to Cu(NO3)2 to NO2 to HNO3 to NH4NO3 to NH3 to NO, we can use the following chemical equations:

1. HNO3 to Cu(NO3)2: - Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O [[1 #9]]

2. Cu(NO3)2 to NO2: - Cu(NO3)2 + H2O → HNO3 + Cu(OH)2 [[1 #10]] - Cu(NO3)2 + H2O → HNO3 + Cu(OH)2 - 2NO2 + O2 → 2NO2 [[1 #7]]

3. NO2 to HNO3: - 4NO2 + O2 + 2H2O → 4HNO3 [[1 #4]]

4. HNO3 to NH4NO3: - NH3 + HNO3 → NH4NO3 [[1 #5]]

5. NH4NO3 to NH3: - NH4NO3 + NaOH → NaNO3 + NH3 + H2O [[1 #6]]

6. NH3 to NO: - 4NH3 + 5O2 → 4NO + 6H2O [[1 #2]]

These equations represent the chemical transformations from HNO3 to Cu(NO3)2 to NO2 to HNO3 to NH4NO3 to NH3 to NO.
