Question

C-CO2-CO-CO2-K2CO3-KHCO3-CO2

Answer 1

C-CO2-CO-CO2-K2CO3-KHCO3-CO2

C+O2=CO2

2CO2=2CO+O2

2CO+O2=2CO2

CO2+K2O=K2CO3

2K2CO3+H2O=2KHCO3+K2O

2KHCO3=2CO2+K2O+H2O

Answer 2

C-CO2-CO-CO2-K2CO3-KHCO3-CO2

1) C+O=2CO

2) 2CO+O2=2CO2

3) CO2 + 2KOH = K2CO3 + H2O

4) K2CO3+H2O+CO2=2KHCO3

5) 2 KHCO3 --> K2CO3 + H2O + CO2

 

Answer 3

The given sequence of compounds is: C-CO2-CO-CO2-K2CO3-KHCO3-CO2.

Let's break down the compounds in the sequence:

1. C: This refers to carbon, which is an element and the basis for organic compounds.

2. CO2: This is carbon dioxide, a molecule composed of one carbon atom bonded to two oxygen atoms. It is a gas that is naturally present in the Earth's atmosphere and produced by various processes, including combustion and respiration.

3. CO: This is carbon monoxide, a molecule consisting of one carbon atom bonded to one oxygen atom. Carbon monoxide is a toxic gas that is formed primarily from incomplete combustion of carbon-containing substances.

4. K2CO3: This is potassium carbonate, a compound composed of two potassium (K) ions and one carbonate (CO3) ion. It is an ionic compound and is commonly used in various industrial processes and as a laboratory reagent.

5. KHCO3: This is potassium bicarbonate, a compound consisting of one potassium (K) ion and one bicarbonate (HCO3) ion. It is also an ionic compound and is often used as an antacid to relieve symptoms of indigestion and heartburn.

6. CO2: Carbon dioxide, as mentioned earlier.

The given sequence represents a combination of carbon-based compounds, including carbon dioxide and carbon monoxide, along with potassium carbonate and potassium bicarbonate. Carbon dioxide appears multiple times in the sequence, suggesting a cycle or interconnected reactions involving the conversion between different carbon compounds and their salts. However, without further context or information, it is challenging to determine the specific purpose or significance of this sequence.
