Question

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

Answer 1

Step by step..........?

Explanation:

Now you now that ammonium specifies a `NH_4^+` cation, and carbonate specifies a `CO_3^(2-)` anion. We add the ions together to get a NEUTRAL formula, and thus `(NH_4)_2CO_3` is the formal result.

On heating this stuff, we may expel a molecule of ammonia to form ammonium bicarbonate......in which electrical neutrality is (and must be) maintained.

`(NH_4)_2CO_3(s) + Delta rarr (NH_4)(HCO_3)(s) + NH_3(g)`
