Final answer:
The correct neutralization reaction of stomach acid with Milk of Magnesia (Mg(OH)2) is 2 HCl(aq) + Mg(OH)2 (aq) → 2 H2O(l) + MgCl2 (aq), which produces water and magnesium chloride as products without generating carbon dioxide gas.
Step-by-step explanation:
Neutralization Reaction of Stomach Acid with Milk of Magnesia
When Milk of Magnesia (Mg(OH)2) is used as an antacid to treat excess stomach acid, it undergoes a neutralization reaction with hydrochloric acid (HCl). The correct balanced chemical equation for the neutralization reaction of stomach acid with Milk of Magnesia is:
2 HCl(aq) + Mg(OH)2 (aq) → 2 H2O(l) + MgCl2 (aq)
In this reaction, two moles of hydrochloric acid react with one mole of magnesium hydroxide to form two moles of water and one mole of magnesium chloride (MgCl2), which is the salt produced from this reaction. Unlike some other antacid reactions, this one does not produce carbon dioxide gas.
