Question

Antacids are taken to counterbalance excess hydrochloric acid, HCl, in the stomach. Complete and balance the following neutralization reactions involving various antacid tablets. If there should be only one mole of the product or reagent in the reaction, then leave the option blank. (A blank answer corresponds to 1 and coefficients of 1 are not expressly written in chemical formulas.)
2, 3, CaCl2, CaCl, MgCl2, 4, MgCl (<-------The options to choose from)
______CaCO3+______HCl -----> _______ /_______+_______H2O+_______CO2
Mg(OH)2+ ______HCl------>________ /________+________H2O
Balance each element on each side of the reaction arrow by adding coefficients to the reactants and products.
The antacid Brioschi, which has been used to relieve heartburn, is mainly sodium bicarbonate. Predict the products, then write the balanced neutralization reaction for the antacid Brioschi in the stomach where the main acid present is hydrochloric acid, HCl.
Express your answer as a chemical equation.

Answer 1

Answer:

1. CaCO3 + 2HCl —> CaCl2 + H2O + CO2

2. Mg(OH)2 + 2HCl —> MgCl2 + 2H2O

3. Na2CO3 + 2HCl —> 2NaCl + H2O + CO2
