which compound forms a powerful acid and also contains a halogen?\n○ h₂s\n○ hbr\n○ li2o\n○ libr

Answer

Brief Explanations:

  1. Analyze each option:
    • $\ce{H2S}$ is hydrogen - sulfide. It forms a weak acid (hydrosulfuric acid) and does not contain a halogen.
    • $\ce{HBr}$ is hydrogen - bromide. When dissolved in water, it forms hydrobromic acid, which is a strong acid. Bromine ($Br$) is a halogen.
    • $\ce{Li2O}$ is lithium oxide. It is a basic oxide and does not form an acid and does not contain a halogen.
    • $\ce{LiBr}$ is lithium bromide. It is a salt and does not form an acid by itself.

Answer:

B. $\ce{HBr}$
