b. which reactant is limiting agent and why?
c.how much lead chromate is generated in grams?
d.what are the concentrations of [CrO4]^-2 and [Pb^+2] (ksp= 1.8*10^-14).
Which families of organic compound does butane transform to in hydrogenation reaction? If no reaction would likely to occur, choose "No reaction."
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
