| Just a little comment about the reaction questions. I personally thought they were the easiest of any reaction Q I've seen, but then again, my teacher did prepare us with weekly quizzes for a little. I mean, a electrochem rxn, a combustion rxn, and a few others were really simple.
I chose:
Zn + Ni+2 => Zn+2 + Ni (battery)
C2H2 + O2 => CO2 + H2O (combustion)
Li + N2 => Li3N (appeared on a previous test)
BF3 + NH3 => BF3NH3 (appeared on a previous test)
Pb+2 + I- => PbI2 (common lead iodide demo rxn)
And, with the previous answers given for equilibrium, I agree completely. |
