СРОЧНО! Даю 75 баллов!!!!!!!!!!!!! Осуществите превращения согласно схемам 1)NH4NO2---N2---NH3---NH4NO3---N2O 2) Zn(NO3)2---NO2---KNO3---HNO3---O2 3)N2--NO2---HNO3----NO--NH4NO3

Answer 1

1) NH4NO2 = N2 + H2O
N2 + H2 = NH3
NH3+HNO3=NH4NO3
NH4NO3 = N2O + H2O 

2) Zn(NO3)2 = ZnO + NO2 + O2
NO2 + KOH = KNO3 + H2O
KNO3 + H2SO4 = HNO3 + KHSO4
HNO3 =NO2 + H2O + O2 

3) N2 + O2 = NO2
NO2 + H2O + O2 ->HNO3
HCl + HNO3 = NO + Cl2 + H2O
 NH3 + H2O + NO = NH4NO3

Answer 2

Transformation 1: NH4NO2 -> N2 -> NH3 -> NH4NO3 -> N2O

The given chemical transformation involves several steps. Let's break it down:

1. NH4NO2 -> N2: - Ammonium nitrite (NH4NO2) decomposes into nitrogen gas (N2) and water (H2O) when heated or subjected to a shock. - The balanced equation for this reaction is: 2NH4NO2 -> 2N2 + 4H2O [[1]].

2. N2 -> NH3: - Nitrogen gas (N2) can be converted into ammonia (NH3) through a process called Haber-Bosch process. - In this process, nitrogen gas reacts with hydrogen gas (H2) in the presence of a catalyst (usually iron) and high pressure. - The balanced equation for this reaction is: N2 + 3H2 -> 2NH3 [[2]].

3. NH3 -> NH4NO3: - Ammonia (NH3) can react with nitric acid (HNO3) to form ammonium nitrate (NH4NO3). - The balanced equation for this reaction is: NH3 + HNO3 -> NH4NO3 [[3]].

4. NH4NO3 -> N2O: - Ammonium nitrate (NH4NO3) can decompose into nitrogen gas (N2) and nitrous oxide (N2O) when heated. - The balanced equation for this reaction is: 2NH4NO3 -> 2N2O + 4H2O + O2 [[4]].

Therefore, the complete transformation is as follows: NH4NO2 -> N2 -> NH3 -> NH4NO3 -> N2O.

Transformation 2: Zn(NO3)2 -> NO2 -> KNO3 -> HNO3 -> O2

Let's break down the given chemical transformation:

1. Zn(NO3)2 -> NO2: - Zinc nitrate (Zn(NO3)2) can decompose into nitrogen dioxide (NO2) when heated. - The balanced equation for this reaction is: 2Zn(NO3)2 -> 2ZnO + 4NO2 + O2 [[5]].

2. NO2 -> KNO3: - Nitrogen dioxide (NO2) can react with potassium hydroxide (KOH) to form potassium nitrate (KNO3). - The balanced equation for this reaction is: 2NO2 + 2KOH -> KNO3 + KNO2 + H2O [[6]].

3. KNO3 -> HNO3: - Potassium nitrate (KNO3) can be converted into nitric acid (HNO3) through a process called Ostwald process. - In this process, potassium nitrate is heated with concentrated sulfuric acid (H2SO4), and the resulting nitric acid is then distilled. - The balanced equation for this reaction is: KNO3 + H2SO4 -> KHSO4 + HNO3 [[7]].

4. HNO3 -> O2: - Nitric acid (HNO3) can decompose into oxygen gas (O2) and nitrogen dioxide (NO2) when heated. - The balanced equation for this reaction is: 4HNO3 -> 2H2O + 4NO2 + O2 [[8]].

Therefore, the complete transformation is as follows: Zn(NO3)2 -> NO2 -> KNO3 -> HNO3 -> O2.

Transformation 3: N2 -> NO2 -> HNO3 -> NO -> NH4NO3

Let's break down the given chemical transformation:

1. N2 -> NO2: - Nitrogen gas (N2) can be converted into nitrogen dioxide (NO2) through a process called oxidation. - The balanced equation for this reaction is: N2 + 2O2 -> 2NO2 [[9]].

2. NO2 -> HNO3: - Nitrogen dioxide (NO2) can react with water (H2O) to form nitric acid (HNO3). - The balanced equation for this reaction is: 3NO2 + H2O -> 2HNO3 + NO [[10]].

3. HNO3 -> NO: - Nitric acid (HNO3) can decompose into nitrogen monoxide (NO), water (H2O), and oxygen gas (O2) when heated. - The balanced equation for this reaction is: 4HNO3 -> 2H2O + 4NO + O2 [[11]].

4. NO -> NH4NO3: - Nitrogen monoxide (NO) can react with ammonia (NH3) to form ammonium nitrate (NH4NO3). - The balanced equation for this reaction is: 4NO + NH3 + 3O2 -> 4NH4NO3 [[12]].

Therefore, the complete transformation is as follows: N2 -> NO2 -> HNO3 -> NO -> NH4NO3.

Please note that these transformations are based on the given information and may not represent practical or commonly used chemical reactions.
