Question

N2–NH3–NH4Cl—NH3–N2–NO—NO2– HNO3–Cu(NO3)2–CuO—Cu

Answer 1

N2 + 3H2 = 2NH3

NH3 + HCl = NH4Cl

NH4Cl + NaOH = NaCl + NH3 + H2O

4NH3 + 3O2 = 2N2 + 6H2O

N2 + O2 = 2NO

2NO + O2 = 2NO2

2NO2 + H2O = HNO3 + HNO2

Cu(OH)2 + 2HNO3 = Cu(NO3)2 + 2H2O

2Cu(NO3)2 —> 2CuO + 4NO2 + O2

CuO + H2 = Cu + H2O

Answer 2

The chemical reaction you've provided seems to involve several steps and compounds. Here's a breakdown of the reaction:

1. N2 (Nitrogen gas) reacts with NH3 (Ammonia) to form NH4Cl (Ammonium chloride). N2 + 3NH3 → 2NH4Cl

2. NH4Cl decomposes to release NH3 and HCl (Hydrochloric acid). NH4Cl → NH3 + HCl

3. NH3 reacts with N2 to form NO (Nitric oxide). 4NH3 + 5O2 → 4NO + 6H2O

4. NO reacts with O2 to form NO2 (Nitrogen dioxide). 2NO + O2 → 2NO2

5. NO2 dissolves in water to form HNO3 (Nitric acid). 3NO2 + H2O → 2HNO3 + NO

6. HNO3 reacts with Cu(NO3)2 (Copper nitrate) to form CuO (Copper(II) oxide). 2HNO3 + Cu(NO3)2 → CuO + 2NO2 + 2H2O

7. CuO reacts with Cu to form Cu2O (Copper(I) oxide). 2CuO + Cu → 3Cu2O

Please note that this is a simplified representation of the reaction pathway, and there might be other intermediates or conditions required for these reactions to occur. Additionally, the reaction conditions such as temperature, pressure, and catalysts may also play a role in the overall reaction.
