1. Chemical Equilibrium Reactions that do not go to completion - why?
Dealing with reversible reactions
Dynamic systems not static
Factors that influence equilibra
How to drive some reactions to completion - disequilibrium

2. reactions that go to completion....
Gas is generated in solution or in a
heterogeneous reaction
Zn (s) HCl (aq) ZnCl2 (aq) H2(g)
Precipitate is formed in a solution
AgNO3(aq) + NaCl(aq) AgCl(s) + NaNO3(aq)
(Use solubility rules to determine)

3. If we heat calcium carbonate in both containers,
what is the difference?
CaCO3(s) CaO(s) CO2 (g)
Open system
CO2 (g) escapes
more CaCO3(s)
decomposes
Closed system
reaction comes
to equilibrium
Could explode too!
