Fe-Cu-CuO-Cu(NO3)2 Reaction Chain

To create a reaction chain starting with Fe and ending with Cu(NO3)2, we need to go through several steps. Here is a detailed explanation of the reaction chain:

1. Fe + CuSO4 = FeSO4 + Cu [[10]](https://textarchive.ru/c-2454871-pall.html) - In this reaction, iron (Fe) reacts with copper sulfate (CuSO4) to form iron sulfate (FeSO4) and copper (Cu).

2. FeSO4 + 2NaOH = Fe(OH)2 + Na2SO4 - Iron sulfate (FeSO4) reacts with sodium hydroxide (NaOH) to form iron hydroxide (Fe(OH)2) and sodium sulfate (Na2SO4).

3. Fe(OH)2 = FeO + H2O - Iron hydroxide (Fe(OH)2) decomposes to form iron oxide (FeO) and water (H2O).

4. FeO + CuO = Fe + Cu - Iron oxide (FeO) reacts with copper oxide (CuO) to regenerate iron (Fe) and copper (Cu).

5. Cu + 2HNO3 = Cu(NO3)2 + H2O + NO2 - Copper (Cu) reacts with nitric acid (HNO3) to form copper nitrate (Cu(NO3)2), water (H2O), and nitrogen dioxide (NO2).

Therefore, the complete reaction chain is as follows: Fe + CuSO4 → FeSO4 + Cu → FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4 → Fe(OH)2 → FeO + H2O → FeO + CuO → Fe + Cu → Cu + 2HNO3 → Cu(NO3)2 + H2O + NO2.
