This is not an equation but the chemical symbol of the cation: Ba2+.
Ba2(SO4)2
NH4+ and Cl- don't react, Only SO42- and Ba2+ do so by forming precipitate: SO42- + Ba2+ --> (BaSO4)s
Ba2+ + [2Cl- + 2Na+] + SO42---> BaSO4 + [2Cl- + 2Na+]Ba2++ SO42- --> BaSO4
At first dissolution reactionBa(OH)2(s) --> Ba2+(aq) + 2OH-(aq)Then precipitation reaction Ba2+(aq) + [SO4 2-](s) --> BaSO4(s)
You're expressing those two reactants as ions. The chemical equation for the reaction between barium and nitrogen is: 3Ba + N2 --> Ba3N2. Or, if you like, the net ionic equation for the formation of the insoluble precipitate barium nitride is: 3Ba+2 + 2N-3 --> Ba3N2.
