NH4NO3 only contains 3 elements, nitrogen, hydrogen, and oxygen. None of the other 115 elements are part of it.
NH4NO3Ammonium nitrate.=============
NH4NO3 + H2O --> NH4+ + NO3- That's the dissolution. (:
The molecular equation is 3Ba(NO3)2(aq) + 2(NH4)3PO4(aq) ==> Ba3(PO4)2(s) + 6NH4NO3(aq)The spectator ions are NH4^+ and NO3^-
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
Nitrate ion, NO3-
NH4NO3Ammonium nitrate.=============
Compound????
(NH4)NO3 + AgNO3 --> (NH4)NO3 + AgNO3
NO3- an NH4+ are polyatomic ions.Co can be a neutral atom or a number of monatomicions.
2NH4+ + SO42- --> (NH4)2SO4
Calcium nitrate is a compound: Ca(NO3)2.
It could be either. For example, a molecule of O2 or Cl2 is an element, but one of CH4 or NO3 is a compound.
NH4NO3 + H2O --> NH4+ + NO3- That's the dissolution. (:
The molecular equation is 3Ba(NO3)2(aq) + 2(NH4)3PO4(aq) ==> Ba3(PO4)2(s) + 6NH4NO3(aq)The spectator ions are NH4^+ and NO3^-
Ammonium sulfate is (NH4)2SO4 (2 ammonium ions on a sulfate ion).
In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
