which compound forms a powerful acid and also contains a halogen?\no h₂s\no hbr\no li2o\no libr

Answer

Brief Explanations:

  1. Recall the properties of halogens and acids. Halogens are elements in group 17 of the periodic - table (F, Cl, Br, I, At). An acid is a substance that can donate a proton (H⁺).
  2. Analyze each option:
    • (H_2S) is hydrogen sulfide. Sulfur is not a halogen.
    • (HBr) is hydrobromic acid. Bromine (Br) is a halogen, and (HBr) is a strong acid in aqueous solution as it dissociates completely to release (H^+) and (Br^-) ions.
    • (Li_2O) is lithium oxide, which is a basic oxide and does not contain a halogen or act as an acid.
    • (LiBr) is lithium bromide, a salt formed by the reaction of lithium hydroxide ((LiOH)) and hydrobromic acid ((HBr)). It is not an acid.

Answer:

B. (HBr)
