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

Explanation:

Sn + 2HBr =  SnBr₂ + H₂

Here HBr is an acid but Sn is not a base . It is a metal . So it is not an acid - base reaction .

HCl + KOH =  KCl + H₂O

HCl is an acid and KOH is a base so it is an acid base reaction.

2AlCl₃ + 3Ca(OH)₂ =  2Al(OH)₃ + 3CaCl₂

It is an acid base reaction . It is so because aluminium hydroxide is a lewis acid and calcium hydroxide is a base . So it is an acid base reaction .

2C₂H₆ +7O₂ =  4CO₂ + 6H₂O

It is not an acid base reaction . It is actually an example of oxidation reaction in which ethane burns in oxygen to give carbon dioxide and water.

i think so it’s will be b yes i believe its

answer carbon and three oxygen atoms;
