Here are the answer to 2017-2018 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) 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)} + K₁Cl_{1 (aq)}
Net Ionic Reaction: 1 Ba²⁺ + CO₃^2- --> 1 Ba₁(CO₃)_{1 (s)}

3. Products: Ba₁(SO₄)_{1 (s)} and Al (s)
Net Ionic Reaction: 3 Ba_(s) + 2 Al ³⁺ + 3 SO₄^2- ---> 3 Ba₁ (SO₄)_{1 (s)} + 2 Al _(s)
