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 + H2O
2HCl + CaCO3 -> CaCl2 + CO2 + H2O
2HCl + Mg(OH)2 -> MgCl2 + 2H2O
6HCl + 2Al -> 2AlCl3 + 3H2
HCl + NaHCO3 -> NaCl + H2O + CO2

I think the correct answer would be HCl + NaHCO3 -> NaCl + H2O + CO2, 2HCl + CaCO3 -> CaCl2 + CO2 + H2O, 2HCl + Mg(OH)2 -> MgCl2 + 2H2O. Hydrochloic acid would react with the basic substances in the stomach which are magnesium hydroxide, sodium bicarbonate and calcium carbonate.

An Enzyme is a biolytic converter that converts the larger molecules to the smaller molecules. These enzymes are made up of protein and help to increase the efficiency of the reaction.

In the stomach, the gland present in the stomach is a gastric gland that secretes the gastric juice. Gastric juice contains pepsin and HCl.

The HCL creates the acidic condition in the stomach, to neutralize it the basic compound is used.

These reactions, which is basic in nature are as follows:-

[tex]2HCl + CaCO_3 -> CaCl_2 + CO_2 + H_2O[/tex]

[tex]HCl + NaHCO_3 -> NaCl + H_2O + CO_2[/tex]

These are the reaction that neutralizes the acidic behavior.
