Question

complete the table below.
some binary molecular compounds
name | chemical formula
sulfur monochloride |
pentasulfur dinitride |
sulfur tetrachloride |
sulfur diiodide |

Explanation:

To determine the chemical formulas of binary molecular compounds, we use the prefixes in the name to indicate the number of atoms of each element. The prefixes are: mono- (1), di- (2), tri- (3), tetra- (4), penta- (5), hexa- (6), etc. The first element in the name is usually written first in the formula, followed by the second element with its ending changed to -ide.

Step 1: Sulfur Monochloride

• The prefix "mono-" for chlorine indicates 1 chlorine atom.
• Sulfur (S) has no prefix, so it is 1 sulfur atom.
• Formula: \( SCl \)

Step 2: Pentasulfur Dinitride

• The prefix "penta-" for sulfur indicates 5 sulfur atoms.
• The prefix "di-" for nitrogen (nitride) indicates 2 nitrogen atoms.
• Formula: \( S_5N_2 \)

Step 3: Sulfur Tetrachloride

• The prefix "tetra-" for chlorine indicates 4 chlorine atoms.
• Sulfur (S) has no prefix, so it is 1 sulfur atom.
• Formula: \( SCl_4 \)

Step 4: Sulfur Diiodide

• The prefix "di-" for iodine (iodide) indicates 2 iodine atoms.
• Sulfur (S) has no prefix, so it is 1 sulfur atom.
• Formula: \( SI_2 \)

Answer:

Name	Chemical Formula
pentasulfur dinitride	\( S_5N_2 \)
sulfur tetrachloride	\( SCl_4 \)
sulfur diiodide	\( SI_2 \)
