(a)[2]
Complete the table below to show how many of each particle are present in $^{14}\text{C}^{2-}$.
(b)[4]
Describe the observations you would make, if any, during reactions of the following chlorides with water. Write equations for any reactions that happen: $\text{CCl}_4$, $\text{GeCl}_4$, $\text{SnCl}_4$.
(c)[1]
Suggest a reason for any difference in the reactivities of the chlorides in (b).
(d)[3]
Use data from the Data Booklet to explain why an aqueous solution of $\text{SnCl}_2$ reacts with $\text{Cl}_2(\text{g})$ whereas an aqueous solution of $\text{PbCl}_2$ does not. Write an equation for the reaction.
