Write the complete balanced equation for the reaction between CaCO3 and KCI
EleoNora [17]

CaCO3 + 2KCL ⇒ CaCl2 + K2CO3

It is balanced as so based on the charges given on the periodic table and polyatomic ions.

Calcium has the charge of 2 but CO3 also shares the same charge, thus cancelling that out.

Potassium has a charge of 1 while Chlorine also shares a charge of 1, also cancelling it out.

Thus, if it performs a double replacement reaction, they would take these charges to the new elements that do not cancel out their charges.

Therefore, we need the coefficient of 2 in front of Potassium Chloride in order to balance the equation as on the products side of the equation, Potassium and Chlorine both have a subscript of 2.

Hope this helps!
