Answer 1

СаСО3 + Н2О + СО2 = Са(НСО3)2

СаСО3 + Н2О + СО2 = Са+2НСО3

Answer 2

Writing the Reaction in Ionic Form

The reaction you provided is: CaCO3 + H2O + CO2 = Ca(HCO3)2. To write this reaction in ionic form, we need to break down the compounds into their respective ions.

The ionic form of the reaction is as follows:

CaCO3 + H2O + CO2 → Ca^2+ + 2HCO3^-

Let's break down the compounds:

- CaCO3 (calcium carbonate) dissociates into Ca^2+ (calcium ions) and CO3^2- (carbonate ions). - H2O (water) remains as H2O. - CO2 (carbon dioxide) does not dissociate into ions.

Now, let's write the ionic form of the reaction:

Ca^2+ + CO3^2- + H2O + CO2 → Ca^2+ + 2HCO3^-

Please note that CO2 does not dissociate into ions, so it remains as CO2 in the reaction.

I hope this helps! Let me know if you have any further questions.
