what is the chemical formula for ammonium carbonate?\n(nh₄)₂co₃\n(nh₄)hco₃\nnh₄(co₃)₂\nnh₄(co₃)
Answer
Brief Explanations:
Ammonium ion is $NH_4^+$ and carbonate ion is $CO_3^{2-}$. To balance the charges, two ammonium ions are needed for one carbonate ion. So the formula is $(NH_4)_2CO_3$.
Answer:
A. $(NH_4)_2CO_3$
