When an acid reacts with a carbonate or metal hydrogen, it forms salts, carbon dioxide gas and water accordingly. Which of the following equations is correct for this chemical reaction?

Na2CO3(s) + 2HCl(aq) → 2NaCl(aq) + 2CO2(g)

Na2CO3(s) + HCl(aq) → 2NaCl(aq) + H2O(l) + 2CO2(g) + H2O(l)

Na2CO3(s) + HCl(aq) → NaCl(aq) + H2O(l) + CO2(g)

Na2CO3(s) + 2HCl(aq) → 2NaCl(aq) + H2O(l) + CO2(g)
