# How do we represent the salt "ammonium carbonate"? How does it decompose upon heating?

Aug 5, 2017

Now you now that ammonium specifies a $N {H}_{4}^{+}$ cation, and carbonate specifies a $C {O}_{3}^{2 -}$ anion. We add the ions together to get a NEUTRAL formula, and thus ${\left(N {H}_{4}\right)}_{2} C {O}_{3}$ is the formal result.
${\left(N {H}_{4}\right)}_{2} C {O}_{3} \left(s\right) + \Delta \rightarrow \left(N {H}_{4}\right) \left(H C {O}_{3}\right) \left(s\right) + N {H}_{3} \left(g\right)$
