Answer:
3 ions are present in [tex](NH_4)_2CO_3[/tex].
Explanation:
Ammonium carbonate is made up two ammonium ions and 1 carbonate ions.
1. Ammonium ion with valency of +1.
2. Carbonate ions with valency of -2.
By Criss-cross method we get:
[tex](NH_3)_2(CO_3)_1[/tex]
When 1 mole of ammonium carbonate is dissolved in water it gives 2 moles of ammonium ions and 1 mole of carbonate ions.The chemical equation is given as:
[tex](NH_4)_2CO_3(aq)\rightarrow 2NH_4^+(aq)+CO_{3}^{2+}(aq)[/tex]
