Part IV
1. Products: Na1(NO3)1 (aq) and K2(SO4)1 (aq)
Net Ionic Reaction: All ions are spectator ions so Reaction does not exist.
2. Products: Ba1(CO3)1 (s) + K1Br1 (aq)
Net Ionic Reaction: 1 Ba2+ + CO32- --> 1 Ba1(CO3)1 (s)
3. Products: Ba1(SO4)1 (s) and Al (s)
Net Ionic Reaction: 3 Ba(s) + 2 Al 3+ + 3 SO42-
---> 3 Ba1 (SO4)1 (s) + 2 Al (s)
