Chapter 10

Element \(A\) burns in nitrogen to give an ionic compound \(B\). Compound \(B\) reacts with water to give \(C\) ' and \(D\). A solution of \(C\) becomes ' milky' on bubbling carbon dioxide. Identify \(A, B, C\) and \(D\).

\(\mathrm{Mg}_{3} \mathrm{~N}_{2}\) when reacted with water gives off \(\mathrm{NH}_{3}\) but \(\mathrm{HCl}\) is not obtained from \(\mathrm{MgCl}_{2}\) on reaction with water at room temperature.

Give briefly the isolation of magnesium from sea water by the Dow process. Give equations for the steps involved.

Write down the balanced equations for the reactions when: Carbon dioxide is passed through a suspension of lime stone in water.
