-14.8
The ions are: Ca2+ and Cl-; the ratio chloride ions/calcium ions is 2.
calcium hydroxide
Aqueous. (Dissolved in water) Example: CaCl2(aq)= Aqueous Calcium Chloride.
CaCl2 is a hygroscopic substance that, if left open with oxygen, will absorb all the H2O from the atmosphere.
because when it is dissolved in water calcium hydroxide is formed
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
2NaCO3 + CaCl2 < > Ca(CO3)2 + 2NaCl
-14.8 Celsius
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.

Carbon dioxide gas is given out! Explanation: calcium carbonate precipitates from mixing calcium chloride solution and sodium carbonate solution, because it has low solubility in water. When it meets strong acid (HCl), it reacts to give out carbon dioxide while forming calcium chloride in the aqueous solution.
