Will Ca(HCO3)2(aq) + 2NH3(aq) react?

Hi,
I'm wondering if an aqueous solution of Calcium Bicarbonate and Ammonia would react to form Ammonium Bicarbonate and Calcium Hydroxide. Additionally, would Calcium Carbonate react with Ammonia in solution to form Ammonium Carbonate?

Which base is stronger, calcium hydroxide, or ammonium hydroxide?

Calcium Hydroxide is a stronger basic. However, in the Solvay Process Ammonium Bicarbonate + Sodium Chloride produces Ammonium Chloride + Sodium Bicarbonate.

Based on this, could Calcium Bicarbonate + Ammonium Carbonate produce Calcium Carbonate + Ammonium Bicarbonate.

What is the driving force behind the Solvay process?

could Calcium Bicarbonate + Ammonium Carbonate produce Calcium Carbonate + Ammonium Bicarbonate.

Good question. At first sight I would say yes, but to be sure you would need to calculate exact equilibrium for the system.
