Here are the answer to 2016-2017 Review Homework for Balancing, Stoichiometry and Predicting Chemical Reaction.
Part I
1) Cu2(C2O4)1
2) Ba1(S1O4)1
3) K1(Mn1O4)1
4) Chromium (II) phosphite
5) Cs1F1
6) Phosphoric acid
7) N3O5
8) Tin (IV) carbonate
9) C1O2
10) H2S1O3
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) + 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)
