Calcium carbonate (CaCO3) reacts with stomach acid (HCl, hydrochloric acid) according to the following equation:
CaCO3(s)+2HCl(aq)?CO2(g)+H2O(l)+CaCl2(aq)
A typical antacid contains CaCO3. If such an antacid is added to 10.0 mL of a solution that is 0.500 M in HCl, how many grams of CO2 gas are produced?
