How would you write the balanced net ionic equation for this rxn?

BaCO3(s) + HCl(aq) -->


I am having trouble figuring out the steps take to write balanced net ionic equation.
Thanks!

My best bet for this one is thinking that this is a double displacement reaction. Meaning:

BaCO3(s) + HCl(aq) ---> H2CO3 (aq) + BaCl2(l or s, I don't know)

Ba stays the same
CO3 changes
H stays the same
Cl changes

Ba + 2Cl --> BaCl2

that's what i got too
answer check smooth op??? 😀

how can you tell which stay the same and while others change?

Look at each molecule (or ion, like CO3) individually and see if it either A) changes phase or B) remains in the same phase. By phase I mean that aq, g, liq, or s.

In the specific case above, Barium and Chloride changed phase, while the other two remained the same. Since they remained the same, they can cancel each other out. When you then do the NIE, you have to also balance it. In this case, Barium is an alkaline-earth metal (it forms a +2 ion), therefore you need 2 Chlorides to balance out the equation.
