Part I
1) Cu2(C2O4)1
2) Ba1(S1O4)1
3) K1(Mn1O4)1
4) Chromium (II) phosphite
5) Cs1F1
6) Potassium phosphate
7) N3O5
8) Tin (IV) carbonate
9) C1O2
10) Hg2Br2
Part II
1) 3,2,1,6 (Double Replacement)
2) 1,3,1,2 (Decomposition)
3) 2,25,16,18 (Combustion)
Part III
1)54.8g Ca1Br2
2)8.83E23 molecules H2O1
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) + K1Cl1 (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)
