Explanation:
Answer: BaCO3(s) + 2H+(aq) --> Ba+2 + H2O(l) + CO2(g)
Explanation: Net ionic equations show only the species or atoms that participate in the reaction, in this case gas-forming
When solid barium carbonate is combined with excess aqueous hydroiodic acid the reaction that take place is.
BaCO3(s) + 2HI(aq) --> BaI2 (aq) + H2O(l) + CO2(g)
To write a ionic equation is necesary to separte the species that are dissociated in water (ag) and expresed it as ions showing the charge
BaCO3(s) + 2I-(aq) + 2H+(aq) --> Ba+2 + 2I- (aq) + H2O(l) + CO2(g)
Since I- is present in both sides of the reaction, it's eliminated in the net ionic equation, and the final expression is:
BaCO3(s) + 2H+(aq) --> Ba+2 + H2O(l) + CO2(g)
