How do you write balanced chemical, complete ionic, and net ionic equations for each of the following reactions?

a. Aqueous solutions of lead (II) nitrate and ammonium chloride are mixed, forming a precipitate of lead (II) chloride. b. Aqueous solutions of aluminum chloride and sodium carbonate are combined, producing solid aluminum carbonate.

$P b {\left(N {O}_{3}\right)}_{2} \left(a q\right) + 2 N {H}_{4} C l \left(a q\right) \rightarrow P b C {l}_{2} \left(s\right) \downarrow + 2 N {H}_{4} N {O}_{3} \left(a q\right)$

Explanation:

And the net ionic equation only represents macroscopic change:

$P {b}^{2 +} + 2 C {l}^{-} \rightarrow P b C {l}_{2} \left(s\right) \downarrow$

I leave it to you to write the chemical equation in words.

And:

$2 A l C {l}_{3} \left(a q\right) + 3 N {a}_{2} C {O}_{3} \left(a q\right) \rightarrow A {l}_{2} {\left(C {O}_{3}\right)}_{3} \left(s\right) \downarrow + 6 N a C l \left(a q\right)$

$2 A {l}^{3 +} + 3 C {O}_{3}^{2 -} \rightarrow A {l}_{2} {\left(C {O}_{3}\right)}_{3} \left(s\right) \downarrow$
