I have a whole series of equations that I've been doing pretty good on - and I'm almost done and I'm stuck! This is what I have so far but I don't think I'm right...
K2CO3(aq) + Ba(NO3)2(aq) --> 2BaCO3 + 2K2NO3?
Also, any advice on this next one would be greatly appreciated..
HCl(aq) + AgNO3(aq) --> HNO3 +AgCl?

You do not need 2 BaCO3's.
2HCl + Ag2NO3 --> H2NO3 + 2AgCl

On the first equation, you would write the last product 2KNO3 instead of 2K2NO3 and since you only have 1 Ba on the left, you only need 1 Ba on the right.
On the second equation, you have it balanced; your question mark should be a (s) or down arrow to indicate precipitation of this insoluble substance. AgCl is the right formula for it , though.
As a matter of fact, BaCO3 is also water insoluble, so it should also have that notation. Both of these reactions are metathesis reactions and also precipitation reactions.

it should be 2KNO3 and 1BaCO3
K+ NO3- Ba++ CO3-- so you need a
ypu second one is correct agcl is a solid its a good way to test water for chlorin add silvernitrate and a percipitate forms.
