# 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:

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

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