Hey there!:

As per solubility rules inorganic compounds that are soluble are

:Ammonium (NH4⁺),potassium (K⁺), sodium (Na⁺) : All ammonium, potassium and sodium salts are soluble. Exceptions:some transition metal compounds.

Bromides (Br⁻), chlorides (Cl⁻) and iodides (I⁻): Most bromides are soluble. Exceptions: salts containing silver, lead, and mercury.


So Rb2Cl2 is expected to be soluble.


 As per solubility rules inorganic compounds that are insoluble are  : Carbonates (CO₃²⁻), chromates (CrO₄²⁻), phosphates (PO₄³⁻), silicates (SiO₄²⁻): All carbonates, chromates, phosphates and silicates are insoluble. Exceptions: those of ammonium, potassium and sodium.


So CaCO3 is insoluble and precipitates

Therefore:

The completed equation is  :


Rb2CO3(aq)  + CaCl2(aq) → CaCO3(s) + Rb2Cl2(aq)


Hope that helps!

Can anyone help me with this?:(
Kobotan [32]

I believe this would be an exothermic reaction, As time increases, the temperature goes up meaning the heat from the system is going into the surroundings. Which indicates an exothermic reaction.
