Final answer:
Balanced chemical equations for acid/base neutralization reactions involve combining an antacid with HCl to form a salt, water, and sometimes a gas. Each reactant and product must have the same number of atoms of each element.
Step-by-step explanation:
The question is asking for balanced chemical equations for acid/base neutralization reactions between different antacid active ingredients and hydrochloric acid (HCl). Here are three examples, assuming the antacids are calcium carbonate (CaCO3), magnesium hydroxide (Mg(OH)2), and sodium bicarbonate (NaHCO3):
- Calcium carbonate and HCl: CaCO3(s) + 2HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
- Magnesium hydroxide and HCl: Mg(OH)2(s) + 2HCl(aq) → MgCl2(aq) + 2H2O(l)
- Sodium bicarbonate and HCl: NaHCO3(s) + HCl(aq) → NaCl(aq) + H2O(l) + CO2(g)
When an antacid reacts with hydrochloric acid, the products typically include salt, water, and sometimes gas, depending on the specific reactants. It's important to ensure the chemical equation is balanced, meaning it has the same number of each type of atom on both the reactant and product sides.
