Answer 1

$CaO + 2HCl=CaCl_2+H_2O \\ CaCl_2+Na_2CO_3=CaCO_3\downarrow+2NaCl \\ CaCO_3=t=CaO+CO_2\uparrow$

Answer 2

Chemical Reaction Transformation:

To perform the transformation of the given chemical compounds, we'll start with the provided compounds: Calcium oxide, calcium chloride, calcium carbonate, and carbon(IV) oxide. We'll then express their equations for the reaction.

1. Calcium oxide: CaO 2. Calcium chloride: CaCl2 3. Calcium carbonate: CaCO3 4. Carbon(IV) oxide: CO2

Chemical Equations for the Reactions:

1. Calcium oxide to calcium chloride: - The reaction for the transformation of calcium oxide to calcium chloride involves the reaction with hydrochloric acid. - The balanced chemical equation is: ``` CaO + 2HCl → CaCl2 + H2O ```

2. Calcium chloride to calcium carbonate: - The transformation of calcium chloride to calcium carbonate can be achieved through a precipitation reaction. - The balanced chemical equation is: ``` CaCl2 + Na2CO3 → CaCO3 + 2NaCl ```

3. Calcium carbonate to carbon(IV) oxide: - The decomposition of calcium carbonate into calcium oxide and carbon(IV) oxide can be represented by the following balanced chemical equation: ``` CaCO3 → CaO + CO2 ```

Conclusion:

The transformation of the given chemical compounds involves a series of chemical reactions, each with its own balanced chemical equation. By following these reactions, we can see how the compounds are interconverted through specific chemical processes.
