1. The thermal decomposition of calcium carbonate (if you think to this reaction) is not an acid-base reaction.
2 The calcium oxide is not oxidized by oxygen.
The balanced equation is: CaCl2 + H2CO3 -> CaCO3 + 2HCl. So, the coefficient needed is 2 in front of HCl to balance the reaction.
When NaHCO3 is combined with CaCl2 and H2O, a reaction will occur. However, the specific products depend on the conditions of the reaction - typically, NaHCO3 will react with CaCl2 to form NaCl, CaCO3, and H2O.
The reaction you provided is a double displacement reaction. In this reaction, calcium carbonate (CaCO3) reacts with sulfuric acid (H2SO4) to produce calcium sulfate (CaSO4), water (H2), and carbon dioxide (CO2).
This chemical equation represents a decomposition reaction, where calcium carbonate (CaHCO3) breaks down into calcium carbonate (CaCO3), water (H2O), and carbon dioxide (CO2) when heat is applied.
The net ionic equation for the reaction between Na2CO3 and CaCl2 to form CaCO3 is: 2Na+ + CO3^2- + Ca^2+ + 2Cl- → CaCO3(s) + 2Na+ + 2Cl-. This equation represents the ions that are involved in the reaction, excluding spectator ions.
The balanced equation for the reaction between hydrochloric acid (HCl) and calcium carbonate (CaCO3) is: 2HCl + CaCO3 -> CaCl2 + H2O + CO2.

The net ionic equation for the reaction between Na2CO3 and CaCl2 to form CaCO3 is: 2Na+ + CO3^2- + Ca^2+ + 2Cl- → CaCO3(s) + 2Na+ + 2Cl-. This equation represents the ions that are involved in the reaction, excluding spectator ions.
The complete ionic equation for the reaction is: Ca^2+(aq) + 2NO3^-(aq) + 2K+(aq) + CO3^2-(aq) --> CaCO3(s) + 2K+(aq) + 2NO3^-(aq)
The products of the reaction between Na2CO3 (sodium carbonate) and Ca(OH)2 (calcium hydroxide) are NaOH (sodium hydroxide) and CaCO3 (calcium carbonate).
The equation is Ca(OH)2 + CO2 = CaCO3 + H2O.
The chemical reaction between CaCO3 and 2H2O results in the formation of Ca(OH)2 (calcium hydroxide) and CO2 (carbon dioxide). The balanced equation for this reaction is: CaCO3 + 2H2O -> Ca(OH)2 + CO2.
