Question

Выполните превращение СаО-Са (ОН)2- СаСО3 - СО2-СаСО3

Answer 1

CaO + H2O = Ca(OH)2
Ca(OH)2 + CO2 = CaCO3 + H2O
CaCO3 = CaO + CO2 (над равно знак t)
CO2 + CaO = CaCO3

Answer 2

Chemical Equation Transformation

To transform the chemical equation CaO - Ca(OH)2 - CaCO3 - CO2 - CaCO3, we can break it down step by step.

1. CaO - Ca(OH)2 - The reaction between CaO and water (H2O) produces Ca(OH)2. - The balanced chemical equation for this reaction is: ``` CaO + H2O → Ca(OH)2 ```

2. Ca(OH)2 - CaCO3 - CO2 - The reaction between Ca(OH)2 and CO2 produces CaCO3. - The balanced chemical equation for this reaction is: ``` Ca(OH)2 + CO2 → CaCO3 + H2O ```

3. CaCO3 - CO2 - CaCO3 - This step seems to be a repetition of the previous step, where CaCO3 is converted to CO2 and then back to CaCO3. It's essentially a reversible reaction.

Therefore, the overall transformation of the given chemical equation can be represented as: ``` CaO + H2O → Ca(OH)2 Ca(OH)2 + CO2 → CaCO3 + H2O ```

These transformations represent the chemical reactions involved in the given equation.
