Цепочка превращенииNH4NO3 ---- N2----- NO ----- NO2------ HNO3------ Cu(NO3)2 ------ Cu(OH)2-------- CuO

Answer 1

NH4NO3 ----t---> N2O +  2H2O,  2N2O ---> 2N2 + O2
N2 + O2 = 2NO
2NO + O2 = NO2
4NO2 + O2 + 2H2O = 4HNO3
4HNO3(конц)  + Cu = Cu(NO3)2 + 2H2O + 2No2
Cu(NO3)2 + 2KOH = 2KNO3 + Cu(OH)2
Cu(OH)2 --t---> CuO + H2O

Answer 2

2NH4NO3=2N2+O2+4H2O
N2+O2=2NO
2NO+O2=2NO2
4NO2+2H2O+O2=4HNO3
CuCO3+2HNO3=Cu(NO3)2+H2O+CO2
Cu(NO3)2+2NaOH=Cu(OH)2+2NaNO3
Cu(OH)2=CuO+H2O

Answer 3

Chemical Reaction Chain:

The transformation of NH4NO3 to CuO involves several intermediate steps. Here's the detailed chain of reactions:

1. NH4NO3 to N2: - NH4NO3 decomposes to produce N2 gas and water vapor. - Reaction: `NH4NO3 → N2 + 2H2O`.

2. N2 to NO to NO2 to HNO3: - N2 reacts with hydrogen to produce ammonia (NH3). - NH3 is then oxidized to form NO, which further oxidizes to form NO2. - NO2 reacts with water to form nitric acid (HNO3). - Reactions: - `N2 + 3H2 → 2NH3`. - `4NH3 + 5O2 → 4NO + 6H2O`. - `2NO + O2 → 2NO2`. - `4NO2 + O2 + 2H2O → 4HNO3` [[1]](https://uchi.ru/otvety/questions/osuschestvite-prevrascheniya-1-1-n2-nh3-no-no2-hno3-nh4no3-nh3-n2-mg3n2-nh3-nh4cl-hcl-2-n).

3. HNO3 to Cu(NO3)2: - Copper (Cu) reacts with nitric acid (HNO3) to form copper(II) nitrate (Cu(NO3)2) and nitrogen dioxide (NO2). - Reaction: `Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O` [[2]](https://lensky-kray.ru/uploads/%D0%95%D0%A2%D0%9D/%D0%91%D0%95%D0%9B%D0%90%D0%92%D0%98%D0%9D%20%D0%B7%D0%B0%D0%B4%D0%B0%D1%87%D0%BD%D0%B8%D0%BA.pdf).

4. Cu(NO3)2 to Cu(OH)2: - Copper(II) nitrate (Cu(NO3)2) reacts with water to form copper(II) hydroxide (Cu(OH)2) and nitric acid (HNO3). - Reaction: `Cu(NO3)2 + 2H2O → Cu(OH)2 + 2HNO3` [[3]](https://mzz.misis.ru/wp-content/uploads/2015/09/Himiya_3_vyvod.pdf).

5. Cu(OH)2 to CuO: - Copper(II) hydroxide (Cu(OH)2) decomposes to form copper(II) oxide (CuO) and water. - Reaction: `Cu(OH)2 → CuO + H2O` [[10]](https://invat.blob.core.windows.net/manuals/9%20%D0%BA%D0%BB%D0%B0%D1%81%D1%81-ru-%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F-2016-.pdf).

Summary:

The complete transformation of NH4NO3 to CuO involves a series of chemical reactions, including decomposition, oxidation, and complex formation, ultimately leading to the formation of copper(II) oxide.
