Asked by Emmaline

Do a cation of Mg^+2 and an anion of CO3^-2 become Mg(CO)3 or magnesium carbonite?

What about (NH4)2 SO4. What cation and anion does that become? I'm not seeing why SO would get 4 if it already has that to begin with. Thank you!

MgCO3 is magnesium carbonate. I don't know of a magnesium carbonite.
NH4SO4 ionizes as follows:
(NH4)2SO4 ==> 2NH4^+ + SO4^=
I don't understand your statement about the SO4. The 4 is a subscript and we assume on these boards that you know that. It would be written as
(NH<sub>4</sub>)<sub>2</sub>SO<sub>4</sub> becomes
2NH<sub>4</sub><sup>+</sup> + SO<sub>4</sub><sup>=</sup>
I hope that comes out ok.

MgCO3
One has a 2 charge and the other has a -2 charge. they both neutralize.


For the (NH4)2 SO4

NH4 has a +1 charge and SO4 has a -2 charge

As you can see from
(NH4)2 SO4

The 2 outside that paranthesis makes the charge a positive 2 which then makes the compound neutralized.

Sorry if my explanation is hard to understand.
