These species are both polyatomic ions.
NH4 + (ammonium )
and
SO4 2- ( sulfate )
combine with opposite charges to form
(NH4)2SO4
which is
ammonium sulfate
a polyatomic ionic bonding.
acidic
Ammonium sulfate
132.15 amu
0.758 moles of NH3 is the amount of moles in 50 grams of NH42SO4.
there is no charge. NH4 has a plus one charge and sulfate (SO4) has a minus two charge. since there is two NH4 the charges balance out
It is ionic
IONIC BOND
A ionic bond formed by,the cations,2K +and the anion,O 2-K2O===== Potassium oxide
Strontium nitride is ionic. Its ionic formulation is Sr2+3 (N3-)2
Ionic. All potassium compounds are ionic.
MgO is ionic because it is a bond between a metal(Mg) and a non-metal(O).
