Question

CO2-K2CO3-KHCO3-K2O-KOH-KCL

Answer 1

СO2 +K2O=K2CO3
K2CO3+H2O+CO2=2KHCO3
2KHCO3 = K2O +CO2 +H2O     (нагревание без доступа кислорода)
K2O+H2O = 2KOH
KOH+HCl= KCl +H2O

Answer 2

The items listed appear to be chemical compounds or elements.

• CO2 is carbon dioxide, a colorless gas that is a byproduct of respiration and combustion processes.
• K2CO3 is potassium carbonate, a white salt that is used in the production of soap, glass, and other chemicals.
• KHCO3 is potassium bicarbonate, a white crystalline powder that is used as a food additive, fire extinguisher, and in other applications.
• K2O is potassium oxide, a white solid that is used in the production of glass and ceramics.
• KOH is potassium hydroxide, a strong alkaline compound that is used in the production of soap and other chemicals.
• KCl is potassium chloride, a colorless crystalline salt that is used as a fertilizer, in medicine, and in other applications.

These compounds can be related to each other through chemical reactions and transformations, as they contain some of the same elements (carbon, oxygen, hydrogen, potassium, and chlorine) and can undergo various reactions to form new compounds.
