what is the formula for hydrobromic acid?
hbro₃
hbro₂
hbro
hbr

Explanation:

Hydrobromic acid is a binary acid (composed of hydrogen and a non - metal). Binary acids have the naming pattern "hydro - (root of non - metal) - ic acid". For hydrobromic acid, the non - metal is bromine (Br). The formula for a binary acid formed with hydrogen (H⁺) and bromide ion (Br⁻) is determined by the combination of H⁺ and Br⁻. Since the charge of H⁺ is + 1 and the charge of Br⁻ is - 1, they combine in a 1:1 ratio, so the formula is HBr.

Answer:

D. HBr
