A certain brand of antacid chewing gum was sent to the lab for testing and it was found to have 15% by mass of hydrotalcite, Mg6Al2(OH)16.4H2O. The active component is the carbonate anion. Each mole of hydrotalcite reacts with 2 moles of hydrochloric acid in the stomach to give carbon dioxide, water and a soluble ionic salt. write a balanced equation for the reaction involving hydrotalcite and the hydrochloric acid.
