Certainly! Let's provide the names and chemical formulas for two polyatomic anions as requested in the table:
[tex]\[
\begin{array}{|c|c|}
\hline
\multicolumn{2}{|c|}{ \text{Two Polyatomic Anions} } \\
\hline
\text{name} & \text{chemical formula} \\
\hline
\text{Nitrite anion} & \text{NO}_2^{-} \\
\hline
\text{Bromite anion} & \text{BrO}_2^{-} \\
\hline
\end{array}
\][/tex]
Let's explain the entries:
1. The nitrite anion, which is denoted as [tex]\( \text{NO}_2^{-} \)[/tex].
2. The bromite anion is represented by the chemical formula [tex]\( \text{BrO}_2^{-} \)[/tex].
This completes the table with the requested information on polyatomic anions.
