Which compound is most likely a powerful and dangerous acid? h2s hbr li2o libr

HBr is the most powerful and dangerous acid .

Explanation:

A strong acid is one that instantly disunites or grants its protons in suspension. HBr is a strong acid. HBr is powerful than HCl or HF because the overlapping of a 1s-orbital and a 4p-orbital is surprisingly small, thus the binding is weak so splitting is very easy..

HBr is a powerful and dangerous acid

Explanation:

HBr gives hydronium ions () in its aqueous solution and presence of large amount of ions in the solution makes it corrosive in nature. This is because when these ions present in the solution comes in contact with any of the objects they tends to neutralize their charge and due to this action of ions we observe corrosive nature of an acid.

Chemical equation for HBr dissociating into ions is given as:

Hence ,HBr is a powerful and dangerous acid. Where as are gas , basic oxide and salt respectively.
