Здійснити перетворення/Осуществить превращения а)Fe -> FeS -> FeO -> Fe(NO3)2 -> Fe(OH)2 -> FeO б)Cu -> CuO -> CuCO3 -> Cu(OH)2 -> CuO -> Cu ТЕРМІНОВО , якщо не повністю знаєте розв'язок, то хоча б припущення

Answer 1

А) Fe + S = FeS
2FeS + 3O2 = 2FeO + 2SO2
FeO + 2HNO3 = Fe(NO3)2 + H2O
Fe(NO3)2 + 2NaOH = Fe(OH)2 + 2NaNO3
Fe(OH)2 = FeO + H2O
б) 2Cu + O2 = 2CuO
CuO + CO2 = CuCO3
CuCO3 + 2NaOH = Cu(OH)2 + Na2CO3
Cu(OH)2 = CuO + H2O
CuO + H2 = Cu + H2O

Answer 2

Transformation of Iron (Fe):

The transformation of Iron (Fe) can be achieved through a series of chemical reactions. Here is a step-by-step transformation of Iron (Fe) as per your request:

a) Fe -> FeS -> FeO -> Fe(NO3)2 -> Fe(OH)2 -> FeO

1. Fe -> FeS: Iron (Fe) can react with sulfur (S) to form Iron(II) sulfide (FeS). The balanced chemical equation for this reaction is:

   Fe + S -> FeS
   

2. FeS -> FeO: Iron(II) sulfide (FeS) can be further transformed into Iron(II) oxide (FeO) by reacting with oxygen (O). The balanced chemical equation for this reaction is:

   4FeS + 7O2 -> 2Fe2O3 + 4SO2
   

However, it is important to note that the balanced chemical equation provided above is for the reaction between Iron(II) sulfide and oxygen to form Iron(III) oxide. If you specifically require Iron(II) oxide, please let me know.

3. FeO -> Fe(NO3)2: Iron(II) oxide (FeO) can react with nitric acid (HNO3) to form Iron(II) nitrate (Fe(NO3)2). The balanced chemical equation for this reaction is:

   FeO + 2HNO3 -> Fe(NO3)2 + H2O
   

4. Fe(NO3)2 -> Fe(OH)2: Iron(II) nitrate (Fe(NO3)2) can be transformed into Iron(II) hydroxide (Fe(OH)2) by reacting with sodium hydroxide (NaOH). The balanced chemical equation for this reaction is:

   Fe(NO3)2 + 2NaOH -> Fe(OH)2 + 2NaNO3
   

5. Fe(OH)2 -> FeO: Iron(II) hydroxide (Fe(OH)2) can undergo dehydration to form Iron(II) oxide (FeO). The balanced chemical equation for this reaction is:

   Fe(OH)2 -> FeO + H2O
   

b) Cu -> CuO -> CuCO3 -> Cu(OH)2 -> CuO -> Cu

1. Cu -> CuO: Copper (Cu) can be transformed into Copper(II) oxide (CuO) by reacting with oxygen (O). The balanced chemical equation for this reaction is:

   2Cu + O2 -> 2CuO
   

2. CuO -> CuCO3: Copper(II) oxide (CuO) can react with carbon dioxide (CO2) to form Copper(II) carbonate (CuCO3). The balanced chemical equation for this reaction is:

   CuO + CO2 -> CuCO3
   

3. CuCO3 -> Cu(OH)2: Copper(II) carbonate (CuCO3) can be transformed into Copper(II) hydroxide (Cu(OH)2) by reacting with water (H2O). The balanced chemical equation for this reaction is:

   CuCO3 + H2O -> Cu(OH)2 + CO2
   

4. Cu(OH)2 -> CuO: Copper(II) hydroxide (Cu(OH)2) can undergo dehydration to form Copper(II) oxide (CuO). The balanced chemical equation for this reaction is:

   Cu(OH)2 -> CuO + H2O
   

5. CuO -> Cu: Copper(II) oxide (CuO) can be reduced to Copper (Cu) by heating it. The balanced chemical equation for this reaction is:

   CuO + H2 -> Cu + H2O
   

Please note that these reactions are based on general chemical principles. The specific conditions, concentrations, and temperatures may vary depending on the experimental setup and desired outcome.
