Question

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

Answer 1

B, C, E

Step-by-step explanation:

B. 2HCl + CaCO3 CaCl2 + CO2 + H2O

C. 2HCl + Mg(OH)2 MgCl2 + 2H2O

E. HCl + NaHCO3 NaCl + H2O + CO2

Answer 2

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.
