15.1 Exercise 1

Complete the changes in concentrations for each of the following reactions:

(a)
$\begin{matrix}\text{AgI} \left(s\right) \rightarrow & \text{Ag}^{+} \left(a q\right) & + \text{I}^{−} \left(a q\right) \\ \\ & x & _____\end{matrix}$

(b)
$\begin{matrix}\text{CaCO}_{3} \left(s\right) \rightarrow & \text{Ca}^{\text{2}+} \left(a q\right) + & \text{CO}_{3} ^{\text{2}−} \left(a q\right) \\ \\ & ____ & x\end{matrix}$

(c)
$\begin{matrix}\text{Mg} \left(\text{OH}\right)_{2} \left(s\right) \rightarrow & \text{Mg}^{\text{2}+} \left(a q\right) + & 2 \text{OH}^{−} \left(a q\right) \\ \\ & x & _____\end{matrix}$

(d)
$\begin{matrix}\text{Mg}_{3} \left(\right. \text{PO}_{4} \left.\right)_{2} \left(s\right) \rightarrow & 3 \text{Mg}^{\text{2}+} \left(a q\right) + & 2 \text{PO}_{4} ^{\text{3}−} \left(a q\right) \\ \\ & x & _____\end{matrix}$

(e)
$\begin{matrix}\text{Ca}_{5} \left(\right. \text{PO}_{4} \left.\right)_{3} \text{OH} \left(s\right) \rightarrow & 5 \text{Ca}^{\text{2}+} \left(a q\right) + & 3 \text{PO}_{4} ^{\text{3}−} \left(a q\right) + & \text{OH}^{−} \left(a q\right) \\ \\ & _____ & _____ & x\end{matrix}$
