Question

Навести рівняння реакцій для такого ланцюга перетворень: N2 → NH3 → (NH4)2SO4 → BaSO4 → Ba(NO3)2 → Ba(OH)2 → Cu(OH)2

Answer 1

Ответ:

N₂ + 3H₂ = 2NH₃

2NH₃ + H₂SO₄ = (NH₄)₂SO₄

(NH₄)₂SO₄ + BaCl₂ = BaSO₄ + 2NH₄Cl

BaSO₄ + 2HNO₃ = Ba(NO₃)₂ + H₂SO₄

Ba(NO₃)₂ + 2KOH = Ba(OH)₂ + 2KNO₃

Ba(OH)₂ + CuCl₂ = Cu(OH)₂ + BaCl₂

Answer 2

Equation for the given chemical reactions:

The given chain of transformations can be represented by the following equations:

1. Nitrogen gas (N2) reacts with hydrogen gas (H2) to form ammonia (NH3): N2 + 3H2 → 2NH3 [[1]]

2. Ammonia (NH3) reacts with sulfuric acid (H2SO4) to form ammonium sulfate ((NH4)2SO4): 2NH3 + H2SO4 → (NH4)2SO4 [[2]]

3. Ammonium sulfate ((NH4)2SO4) reacts with barium chloride (BaCl2) to form barium sulfate (BaSO4): (NH4)2SO4 + BaCl2 → BaSO4 + 2NH4Cl [[3]]

4. Barium sulfate (BaSO4) reacts with nitric acid (HNO3) to form barium nitrate (Ba(NO3)2): BaSO4 + 2HNO3 → Ba(NO3)2 + H2SO4 [[4]]

5. Barium nitrate (Ba(NO3)2) reacts with sodium hydroxide (NaOH) to form barium hydroxide (Ba(OH)2): Ba(NO3)2 + 2NaOH → Ba(OH)2 + 2NaNO3 [[5]]

6. Barium hydroxide (Ba(OH)2) reacts with copper(II) sulfate (CuSO4) to form copper(II) hydroxide (Cu(OH)2): Ba(OH)2 + CuSO4 → Cu(OH)2 + BaSO4 [[6]]

Please note that these equations represent the chemical reactions in the given chain of transformations.
