6. Analyze the GC traces from each of the reactions shown below. The GC parameters for each trace are identical: Br. NaOH DCM 3.20 min 3.81 min Br, NaOH DCM 1 2 4 1 2 3.20 min 2.82 min 2.82 min 3.20 min 3.81 min

For the reaction: PbCl2(s) Pb2+(aq) +2C11-(aq), what is Q* when 8.0 mL of 0.050 M lead nitrate is added to 14 mL of 0.031 M sodium chloride? Ksp of lead chloride is 1.6 x 10-5 M³. Hint given in general feedback *Recall: Q is compared to Ksp to determine whether a precipitate forms.

All changes saved 6. You have a very concentrated solution (12 M) of potassium chloride (KCI). You need it to be at the lowest concentration possible for the experiment you are about to conduct. The problem is you forgot to order lab supplies, so you only have 2 L of distilled water left. What would be the final concentration if you added the two 2 L of distilled water to the 0.5 L of 12 M KCI? 3.0 M 2.4 M 24 M 48 M

For 2SO2 (g) + O2 (g) <-------> 2SO3 (g) Concentrations: [SO2]=0.20, [O2]=0.80, [SO3]= 0.43.  What is Kc for the reaction?

How would the equilibrium be affected in regards to the value of Qc or Kc for each of the following conditions?: Fe3+ (aq) + SCN- (aq) ⇌ FeSCN2+ (aq) Adding KSCN (aq) Adding Fe(NO3) (aq) Adding NaF (s) Placing the solution into a hot water bath Placing the solution into an ice bath (To whom this may concern, Could you at least explain one as simply as possible so I'm able to understand the others enough to explain them myself? Thanks in anvance!)
