Here are the answers to [[2020-2021 Review HW for Balancing, Types, Predicting and Energy Change of Chemical Reactions]]. 
 
 
Part I 
1) 3,2,1,6 Double Replacement 
2) 1,3,1,2 Decomposition 
3) 2,25,16,18 Combustion 
4) 4,3,2 Synthesis 
5) 1,3,2,3 Single Replacement 
 
Part II 
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) 
 
 
Part III

1) Activated complex 
2) Greater than 
3) Heat of Reaction (&#916;H) 
4) Absorbs 
5) Activation energy (Eac) 
6) Endothermic
