The chemical reactions involving the compounds mentioned are as follows:

C + CO2 -> Na2CO3CO2 + CaCO2 -> CaCl22Na2CO3 + CaCl2 -> 2CaCO2 + 2NaCl

These reactions represent the formation of sodium carbonate (Na2CO3) from carbon (C) and carbon dioxide (CO2), the formation of calcium chloride (CaCl2) from carbon dioxide (CO2) and calcium carbonate (CaCO2), and the reaction between sodium carbonate (Na2CO3) and calcium chloride (CaCl2) to produce calcium carbonate (CaCO2) and sodium chloride (NaCl).
