Explain why zinc sulfide does not conduct electricity. Refer to Fig. 6.1.
Predict one other physical property of zinc sulfide.
Explain why disulfur dichloride has a low melting point. Refer to Fig. 6.1.
Complete Fig. 6.2 to show the dot-and-cross diagram for the electronic configuration of disulfur dichloride. Include only the outer-shell electrons.
Disulfur dichloride reacts with water as shown. $\text{S}_2\text{Cl}_2 + 3\text{H}_2\text{O} \rightarrow 2\text{HCl} + \text{H}_2\text{S} + \text{H}_2\text{SO}_3$ $13.5\,\text{g}$ of disulfur dichloride is reacted with $8.00\,\text{g}$ of water. Show by calculation that water is in excess.
