To complete the table with the chemical formulas of the given binary molecular compounds, we need to match each compound's name with its corresponding chemical formula.
1. Tetraphosphorus Hexasulfide: The name indicates there are 4 phosphorus atoms and 6 sulfur atoms. Therefore, the chemical formula is [tex]\( \text{P}_4\text{S}_6 \)[/tex].
2. Diphosphorus Pentasulfide: The name indicates there are 2 phosphorus atoms and 5 sulfur atoms. Therefore, the chemical formula is [tex]\( \text{P}_2\text{S}_5 \)[/tex].
3. Tetraphosphorus Disulfide: The name indicates there are 4 phosphorus atoms and 2 sulfur atoms. Therefore, the chemical formula is [tex]\( \text{P}_4\text{S}_2 \)[/tex].
4. Phosphorus Disulfide: The name indicates there is 1 phosphorus atom and 2 sulfur atoms. Therefore, the chemical formula is [tex]\( \text{PS}_2 \)[/tex].
Now, let's complete the table with these formulas:
\begin{tabular}{|c|c|}
\hline
\multicolumn{2}{|c|}{ some binary molecular compounds } \\
\hline
name & chemical formula \\
\hline
tetraphosphorus hexasulfide & [tex]\(\text{P}_4\text{S}_6\)[/tex] \\
\hline
diphosphorus pentasulfide & [tex]\(\text{P}_2\text{S}_5\)[/tex] \\
\hline
tetraphosphorus disulfide & [tex]\(\text{P}_4\text{S}_2\)[/tex] \\
\hline
phosphorus disulfide & [tex]\(\text{PS}_2\)[/tex] \\
\hline
\end{tabular}
