What is the correct formula for the missing product from the equation below: Na2CO3(aq)
+
CaCl2 (aq)
> NaCl +

CaCO3 (s)

Explanation:

This equation is a double replacement equation, which means that since Na and Cl and paired, Ca and CO3 will be paired.

Then, you look at the charge of each element and balance

Ca has a 2+ charge

CO3 has a 2- charge

The 2+ charge and the 2- charge will cancel so there is no need for a  subscript or to balance the equation

The complete equation will be Na2CO3 (aq) + CaCl2(aq) -> NaCl (aq) + CaCO3 (s)

I hope this helps and have a great day!

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
