The main acid in the stomach is hydrochloric acid (HCl). Which chemical equations show a reaction that occurs when someone takes an antacid? Check all that apply.HCl + NaOH NaCl + H2O2HCl + CaCO3 CaCl2 + CO2 + H2O2HCl + Mg(OH)2 MgCl2 + 2H2O6HCl + 2Al 2AlCl3 + 3H2HCl + NaHCO3 NaCl + H2O + CO2

Antacids often contain calcium carbonate, which provides carbonate ions that act as a base. These carbonate ions neutralize stomach acid by accepting free hydrogen ions (H+). This chemical reaction produces water and carbon dioxide gas as products. If the antacid is dissolved before ingestion, the reaction occurs more quickly because the ions are more readily available to react.
Which ideas did you include in your response?Calcium carbonate contains the carbonate ion.Calcium carbonate accepts free H+ ions.When an acid reacts with a carbonate, carbon dioxide gas is one of the products.If antacids are dissolved prior to ingestion, the reaction between carbonate and hydrogen is faster.
