Question

С -> СО2 -> СО -> СО2 -> Х -> Са(НСО3) 2

Answer 1

1) C+O2=CO2

2) CO2+H2=CO+H2O

3) CO+H2O=CO2+H2

4) CO2+CaO=CaCO3

5)CaCO3+CO2+H2O=Ca(HCO3)2

Answer 2

The series of reactions you mentioned involves the conversion of carbon (C) to carbon dioxide (CO2), carbon monoxide (CO), carbon dioxide (CO2) again, and then a compound represented by X, which ultimately reacts with calcium hydroxide (Ca(OH)2) to form calcium bicarbonate (Ca(HCO3)2).

Here is the breakdown of the reactions:

1. C -> CO2: This is the combustion of carbon, where carbon reacts with oxygen (O2) to produce carbon dioxide.

2. CO2 -> CO: This reaction involves the reduction of carbon dioxide to carbon monoxide. It can occur under certain conditions, such as in the presence of a reducing agent like carbon or at high temperatures.

3. CO -> CO2: This reaction represents the oxidation of carbon monoxide back to carbon dioxide. It can occur naturally in the presence of oxygen or through catalytic converters in vehicles.

4. CO2 -> X: The compound X is not specified, so it's unclear what this reaction represents. Without more information, it's challenging to determine the exact reaction involved or the nature of the compound X.

5. X -> Ca(HCO3)2: This reaction involves the reaction of compound X with calcium hydroxide (Ca(OH)2) to form calcium bicarbonate (Ca(HCO3)2). This reaction indicates the formation of a bicarbonate salt involving calcium.

Please provide more information or clarify the reaction involving compound X if you require further assistance.
