Problem- Use LeChatelier's Principle to explain the changes to all four equilibria. Show all chemical reactions, describe what the stress was in each case and how Le Chatelier's principle resulted in the change.
1) Ca(OH)2 (s) <> Ca2+ (aq) + 2OH- (aq)
H+ (aq) + OH- (aq) <> H2O (l)
2) FE3+ (aq) + SCN- (aq) <> (Fe(SCN))2+ (aq)
3) Ni2+ (aq) + 6NH3 (aq) <> (Ni(NH3)6)2+ (aq)
H+ (aq) + NH3 (aq) <> NH4 (aq)
4) 4Cl- (aq) + (Co(h2O)6)2+ (aq) <> (CoCl4)2- (aq) + 6H2O (l)
