Question

Problem Page Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.)

CaCl2 (aq) + H2O(l) →

Answer 1

CaCl2 + H2O Ca2+(aq) + 2Cl-(aq)

Step-by-step explanation:

CaCl2 + H2O Ca2+(aq) + 2Cl-(aq)

When CaCl2 is dissolved in H2O (water) it will dissociate (dissolve) into Ca+2 and Cl- ions.

The dissolution of calcium chloride is an exothermic process.
