Identify the type of reaction when $\text{SCl}_2$ is introduced into water.
Name a chloride of another Period 3 element that is also a liquid at room temperature and forms misty fumes when water is added.
Complete the dot-and-cross diagram in Fig. 2.1 so that it shows the outer-electron arrangement in a molecule of $\text{SCl}_2$. Use $\times$ for electrons from the chlorine atoms. Use $\bullet$ for electrons from the sulfur atom.
Predict the shape of, and bond angle in, a molecule of $\text{SCl}_2$ using VSEPR theory.
Deduce the oxidation numbers of magnesium and nitrogen in magnesium nitride, $\text{Mg}_3\text{N}_2$, to finish Table 2.1.
Magnesium nitride reacts with excess water to form only ammonia and magnesium hydroxide. Construct an equation for this reaction.
Explain why the solution formed in the reaction in (c)(ii) has a pH above 7. Refer to the products of the reaction in your answer.
Use Fig. 2.2 to deduce the empirical formula of boron nitride.
Suggest the identity of another crystalline solid whose atoms are arranged in layers like those in solid boron nitride.
