2. The chemical reaction that occurs when an antacid is prescribed to treat indigestion is represented by the formula: Mg(OH)2 + HCl -> MgCl2 + H2O. Other than water, what compound is produced from this reaction?
Answer: A
Magnesium Chloride is produced from the reaction.
The reaction between magnesium hydroxide and hydrochloric acid yields magnesium chloride and water. Thus, the compound produced, other than water, is magnesium chloride.
A) Magnesium Chloride
This option is correct because, in the provided chemical equation, magnesium chloride (MgCl2) is one of the products formed when magnesium hydroxide reacts with hydrochloric acid. This confirms that magnesium chloride is produced alongside water in the reaction.
B) Magnesium Hydride
Magnesium hydride (MgH2) is incorrect as it is not produced in this reaction. The reaction specifically involves the formation of magnesium chloride and water, and magnesium hydride does not appear in the equation or the reaction context.
C) Magnesium Hydroxide
This option is incorrect because magnesium hydroxide (Mg(OH)2) is one of the reactants in the chemical equation, not a product. The reaction takes magnesium hydroxide and converts it into magnesium chloride and water.
D) Hydrochloric Acid
Hydrochloric acid (HCl) is also incorrect as it is a reactant in the reaction. The equation shows that hydrochloric acid is consumed to produce magnesium chloride and water, rather than being formed as a product.
Conclusion
Magnesium chloride is definitively the correct answer as it is the only compound produced in the reaction alongside water. All other options are either reactants or unrelated compounds that do not result from the reaction presented, thus confirming magnesium chloride as the sole product aside from water.
