Answer 2

Transformation of CaCO2 to CO2- and Na2CO3

To transform CaCO2 into CO2- and Na2CO3, several chemical reactions are involved. Here is the step-by-step process:

1. CaCO2 reacts with water (H2O) to form Ca(OH)2 and CO2 ``` CaCO2 + H2O → Ca(OH)2 + CO2 ```

2. Ca(OH)2 then reacts with Na2CO3 to produce CaCO3 and NaOH ``` Ca(OH)2 + Na2CO3 → CaCO3 + 2NaOH ```

3. CaCO3 can further decompose into CaO and CO2 [[2]](https://uchi.ru/otvety/questions/reshite-tsepochku-prevrascheniy-ca-ca-oh-2-caco3-cao-cacl2-ca-t-bao-ba-oh-2-ba-no3-2-nano): ``` CaCO3 → CaO + CO2 ```

Therefore, the overall reaction can be summarized as follows: ``` CaCO2 + H2O + Na2CO3 → Ca(OH)2 + CO2 + CaCO3 + NaOH ```
