Predict the outcome when the following reactants react together.
When calcium carbonate (CaCO3) reacts with hydrochloric acid (2 HCl), the reaction produces calcium chloride (CaCl2), carbon dioxide (CO2) and water (H2O). The balanced chemical equation for this reaction is:

CaCO3 + 2 HCl → CaCl2 + CO2 + H2O

In this reaction, the hydrochloric acid reacts with the calcium carbonate, releasing carbon dioxide gas and forming calcium chloride and water.
CaCO3 + 2HCl
