Chemistry Structure and Properties

Write Lewis structures for each molecule or ion. Include resonance
structures if necessary and assign formal charges to all atoms. If you
need to, expand the octet on the central atom to lower formal charge.
\begin{equation}\mathrm{ a.} {SO}_{4}^{2-} \quad \text { b. } \mathrm{HSO}_{4}^{-} \quad \text { c. } \mathrm{SO}_{3} \quad \text { d. } \mathrm{BrO}_{2}^{-}\end{equation}
