Which of the following is an acid-base neutralization reaction? (1 point) Sn + 2HBr yields SnBr2 + H2 HCl + KOH yields KCl + H2O 2AlCl3 + 3Ca(OH)2 yields 2Al(OH)3 + 3CaCl2 2C2H6 +7O2 yields 4CO2 + 6H2O

HCl + KOH ⇒ KCl + H₂O

Explanation:

Which of the following is an acid-base neutralization reaction?

Sn + 2HBr ⇒ SnBr₂ + H₂. NO. This is a single displacement reaction.

HCl + KOH ⇒ KCl + H₂O. YES. An acid reacts with a base to form salt and water.

2AlCl₃ + 3Ca(OH)₂ ⇒ 2Al(OH)₃ + 3CaCl₂. NO. This is a double dispacement reaction.

2C₂H₆ +7O₂ ⇒ 4CO₂ + 6H₂O. NO. This is a combustion reaction.

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.
