Question

C->CO2->H2->CO3->K2CO3->BaCO3 Решите цепочку химических уравнений

Answer 1

1. C→CO₂→H₂→H₂CO₃→K₂CO₃→BaCO₃
Проанализировав цепочку превращений из оксида углерода(IV) не возможно получить напрямую водород его можно получить из оксида углерода(ll), ПОЭТОМУ В ЦЕПОЧКУ ПРЕВРАЩЕНИЙ ДОБАВИМ ОКСИД УГЛЕРОДА(ll). ИЗ ВОДОРОДА НЕВОЗМОЖНО ПОЛУЧИТЬ УГОЛЬНУЮ КИСЛОТУ, ПОЭТОМУ В ЦЕПОЧКУ ПРЕВРАЩЕНИЙ ВВОДИМ ВОДУ:
 C→CO₂→CO→H₂→H₂O→H₂CO₃→K₂CO₃→BaCO₃
C+O₂=CO₂
CO₂ + C= 2CO
CO + H₂O ⇄ CO₂ + H₂
2H₂ + O₂= 2H₂O
H₂O + CO₂⇄H₂CO₃
H₂CO₃ + KOH =K₂CO₃+H₂O
K₂CO₃ + BaCI₂ = BaCO₃↓ + 2KCI

Chemical Equations Chain

To solve the given chemical equations chain, we will start with the provided compounds and reactants and proceed step by step to obtain the desired product. Here is the chain of chemical equations:

1. C -> CO2: - The combustion of carbon (C) produces carbon dioxide (CO2). - The balanced equation for this reaction is: C + O2 -> CO2.

2. CO2 -> H2: - The reduction of carbon dioxide (CO2) can produce hydrogen gas (H2). - The balanced equation for this reaction is: CO2 + H2 -> H2O + C.

3. H2 -> CO3: - The reaction of hydrogen gas (H2) with carbon dioxide (CO2) can produce carbonic acid (H2CO3). - The balanced equation for this reaction is: H2 + CO2 -> H2CO3.

4. CO3 -> K2CO3: - The reaction of carbonic acid (H2CO3) with potassium hydroxide (KOH) can produce potassium carbonate (K2CO3). - The balanced equation for this reaction is: H2CO3 + 2KOH -> K2CO3 + 2H2O.

5. K2CO3 -> BaCO3: - The reaction of potassium carbonate (K2CO3) with barium chloride (BaCl2) can produce barium carbonate (BaCO3). - The balanced equation for this reaction is: K2CO3 + BaCl2 -> BaCO3 + 2KCl.

Therefore, the complete chain of chemical equations is as follows:

**C + O2 -> CO2 CO2 + H2 -> H2O + C H2 + CO2 -> H2CO3 H2CO3 + 2KOH -> K2CO3 + 2H2O K2CO3 + BaCl2 -> BaCO3 + 2KCl**

Please note that the provided chain of chemical equations is based on the information available and may not represent the most efficient or practical route for the synthesis of the desired product.
