When solid barium carbonate is added to dilute hydrochloric acid, a reaction occurs forming barium chloride, water, and carbon dioxide gas:
BaCO3(?)+2HCl(?)→BaCl2(?)+H2O(l)+CO2(?) \text{BaCO}_3(\text{?}) + 2\text{HCl}(\text{?}) \rightarrow \text{BaCl}_2(\text{?}) + \text{H}_2\text{O}(\text{l}) + \text{CO}_2(\text{?}) BaCO3(?)+2HCl(?)→BaCl2(?)+H2O(l)+CO2(?)Which of the following shows the correct state symbols to replace the question marks in the equation?
BaCO3(s)\text{BaCO}_3(\text{s})BaCO3(s), HCl(l)\text{HCl}(\text{l})HCl(l), BaCl2(s)\text{BaCl}_2(\text{s})BaCl2(s), CO2(g)\text{CO}_2(\text{g})CO2(g)

BaCO3(aq)\text{BaCO}_3(\text{aq})BaCO3(aq), HCl(aq)\text{HCl}(\text{aq})HCl(aq), BaCl2(s)\text{BaCl}_2(\text{s})BaCl2(s), CO2(aq)\text{CO}_2(\text{aq})CO2(aq)
BaCO3(s)\text{BaCO}_3(\text{s})BaCO3(s), HCl(aq)\text{HCl}(\text{aq})HCl(aq), BaCl2(s)\text{BaCl}_2(\text{s})BaCl2(s), CO2(g)\text{CO}_2(\text{g})CO2(g)
