Highly toxic disulfur decaflouride gas decomposes through a radical reaction to reversily form sulfur tetraflouride and sulfur hexaflouride gases. A 2.00L flask originally containing .500M disulfur decaflouride is allowed to reach equilibrium and found to contain .023M disulfur decaflouride. If an additional .125 mol of the disulfur decaflouride is added and equilibrium reestablished, what will be the concentrations of each component.
Imagine that a chemist has cyclohexanone, triphenylphosphine, butyllithium, and 2-bromobutane.
What is the percent ionization of a 0.186 M solution of this acid? A certain weak base has a Kb of 7.50 × 10-7. What concentration of this base will produce a pH of 10.06?
A 100 mL buffer solution initially has 1.00 M HClO (Ka = 3.0 × 10-8) and 0.75 M NaClO. What is the new pH when this 100 mL of 0.10 M NaOH is added to the initial buffer solution?
Write a mechanism for the reaction of an alkyl halide with alcoholic silver nitrate which depicts the type of substitution which occurs. Explain how this mechanism accounts for the relative rate of reactivity of primary, secondary and tertiary hal..

Aspirin (C9H8O4) is produced through the following reaction of salicylic acid (C7H6O3) and acetic anhydride (C4H6O3). C7H6O3(s) + C4H6O3-> C9H8O4(s) + HC2H3O2
Consider the following data showing the initial rate of a reaction at several different concentrations of A
AMines can be made by the reduction of nitriles, which in turn can be made from an alkyl halide. Draw the structures of a starting alkyl bromide and the intermediate nitrile that would be used in the synthesis
