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

Answer

Answer:

B. HBr

Explanation:

Step1: Identify halogens

Halogens are elements in group 17 of the periodic - table (F, Cl, Br, I, At). Among the options, Br is a halogen present in HBr and LiBr.

Step2: Identify acids

An acid is a substance that can donate a proton (H⁺). H₂S is a weak acid, HBr is a strong acid, Li₂O is a basic oxide, and LiBr is a salt. Since we need a compound that forms a powerful acid and contains a halogen, HBr meets both criteria as it is a strong acid and contains the halogen bromine.
