4.1 Exercise 11

From the balanced molecular equations, write the complete ionic and net ionic equations for the following:

(a) $\text{K}_{2} \text{C}_{2} \text{O}_{4} \left(a q\right) + \text{Ba} (\text{OH})_{2} \left(a q\right) \rightarrow 2 \text{KOH} \left(a q\right) + \text{BaC}_{2} \text{O}_{4} \left(s\right)$

(b) $\text{Pb} \left(\right. \left(\text{N} \text{O}_{3} \left.\right)\right)_{2} \left(a q\right) + \text{H}_{2} \text{SO}_{4} \left(a q\right) \rightarrow \text{PbSO}_{4} \left(s\right) + 2 \text{HNO}_{3} \left(a q\right)$

(c) $\text{CaCO}_{3} \left(s\right) + \text{H}_{2} \text{SO}_{4} \left(a q\right) \rightarrow \text{CaSO}_{4} \left(s\right) + \text{CO}_{2} \left(g\right) + \text{H}_{2} \text{O} \left(l\right)$
