Hi
Ok so this be my balanced equation Na2CO3 + 2HX ->2NaX + H2O + CO2
and tis be my ionic equation Na2^2+(aq) + CO3^2-(aq) + H^+(aq) + X^-(aq) - >Na^+(aq) + X^-(aq) + H2O(l) + CO2(g)
this correct or? if not please explain, not stupid, i just dont really get ionic equations
can you evn do ionic equations with X? or am i gonna have to work out what it is
ALSO, whats best indictor for this?
then I have an ionic equation for CaCO3 and HX
Ca2+(aq) + CO32-(aq)+ H+(aq) + X-(aq) ->Ca2+(aq) + X22-(aq) + H2O(l) + CO2(g), correct? much appreciated for anyone who helps
2Na^2+ (aq) + CO3^2- (aq) +2H^+(aq) + 2X^-(aq)-------------------------->2Na^+(aq) + 2X^- +H2O(l) + CO2 (g)

then cancel out like terms

2Na^+ (aq) + CO3^2- (aq) +2H^+(aq) + 2X^-(aq)-------------------------->2Na^+(aq) + 2X^- +H2O(l) + CO2 (g)

then simplify
CO3^2- (aq) +2H^+(aq) --------------------------> H2O(l) + CO2 (g)

Hi
I'm not so sure how to help you using the X example. But it might be easier if you substitute the X in with an actual chemical. State symbols really help with ionic equations, basically only break ionic substances into their ions and everything else remains intact. Then cancel out things with the same state on either side of the equation and what you're left with is your ionic equation. Sorry I'm not great at explaining but let me know if you need me to show you an example using the method I've tried to explain
