Question

(NH4)3 PO4→NH3→NH4 NO2→N2→NO→NO2→HNO3→Hg(NO3)2→NO2

Answer 1

Ответ:

(NH4)3PO4 → 3 NH3 + H3PO4

HNO2 + NH3 → NH4NO2

3NH4NO2 → N2 + 4NH3 + 3O2

N2 + O2 → 2NO

2NO + O2 → 2NO2

3H2O + 8NO2 → 6HNO3 + N2O

3Hg3N + 26HNO3 → 9Hg(NO3)2 + 11NO + 13H2O

2Hg(NO3)2 → 2HgO + 4NO2 + O2

Answer 2

The chemical reaction sequence you've provided starts with ammonium phosphate ((NH4)3PO4) and goes through a series of reactions to produce nitric acid (HNO3) and mercury(II) nitrate (Hg(NO3)2). Let's break down each step of the sequence:

1. (NH4)3PO4

   • Ammonium phosphate is the starting compound.

2. NH3

   • Ammonium phosphate decomposes into ammonia (NH3) and water (H2O).

3. NH4NO2

   • Ammonia reacts with nitric acid (HNO3) to form ammonium nitrate (NH4NO2).

4. N2

   • Ammonium nitrate decomposes into nitrogen gas (N2) and water (H2O).

5. NO

   • Nitrogen gas (N2) reacts with oxygen gas (O2) to form nitric oxide (NO).

6. NO2

   • Nitric oxide (NO) reacts with oxygen gas (O2) to form nitrogen dioxide (NO2).

7. HNO3

   • Nitrogen dioxide (NO2) reacts with water (H2O) to produce nitric acid (HNO3).

8. Hg(NO3)2

   • Nitric acid (HNO3) reacts with mercury metal (Hg) to produce mercury(II) nitrate (Hg(NO3)2).

The overall reaction sequence is:

(NH4)3PO4 → NH3 → NH4NO2 → N2 → NO → NO2 → HNO3 → Hg(NO3)2

This sequence represents a series of chemical reactions, and each step in the sequence involves various reaction conditions and may require catalysts or specific temperature and pressure conditions. Please note that these reactions may not happen spontaneously in all cases, and in a laboratory setting, you would need to carefully control the conditions to achieve these transformations.
