Answer
Calcium Carbonate and Potassium Bromide will from. The balanced chemical equation is as follows:
$K_{2}CO_{3}(aq) + CaBr_{2}(aq) → CaCO_{3}(s) + 2 KBr(aq) $
Work Step by Step
This is an aqueous double displacement reaction. This means that the anions switch which cations they are paired with.
