which reaction is a neutralization reaction? this one is a al₂(so₄)₃ + ca(oh)₂ → al(oh)₃ + caso₄ this one is…

Answer:

D. HCl + Mg(OH)₂ → H₂O + MgCl₂

Explanation:

Step1: Recall neutralization reaction definition

A neutralization reaction is between an acid and a base to form salt and water.

Step2: Analyze option A

Al₂(SO₄)₃ + Ca(OH)₂ → Al(OH)₃ + CaSO₄ is a double - displacement reaction, not a neutralization as Al₂(SO₄)₃ is not an acid.

Step3: Analyze option B

C₅H₁₂ + O₂ → CO₂ + H₂O is a combustion reaction, not a neutralization.

Step4: Analyze option C

BaCl₂ + H₂SO₄ → BaSO₄ + HCl is a double - displacement reaction. BaCl₂ is not a base.

Step5: Analyze option D

HCl (an acid) reacts with Mg(OH)₂ (a base) to form H₂O and MgCl₂ (salt), which is a neutralization reaction.
