Let's say you are instructed to collect your distillate (condensate) in four separate containers,~1mL in each, during the fractional distillation of 4mL of a (1:1) cyclohexane-toluene mixture, and then obtain IR spectra for each fraction. How would the IR spectrum of the first 1 mL fraction look different from that of the last 1 mL fraction?
If the initial concentration of AB is 0.260 M, and the reaction mixture initially contains no products, what are the concentrations of A and B after 80 s?
The concentration of HCl in a bottle was determined as follows: •3.00 mL of the acid were diluted to 250.00 mL •102.40 mL of the diluted acid were titrated with 0.08212-M NaOH
Formation of SO3 from the air pollutant SO2 is a key step in the formation of acid rain, according to the following reaction. Use standard enthalpies of formation from Appendix L to calculate the enthalpy change for the reaction.
Briefly describe experiments and expected outcomes to differentiate whether this inhibitor is a competitive inhibitor or a mixed inhibitor.
what percentage of HSO4- is dissociated in 2M solution? Why does molarity approximate molality at low concentrations?
Calculate the standard reduction potential for the X half-reaction. The standard reduction potential of the copper half-reaction is 0.52 V. (Hint, write the half-reactions and the overall chemical equation for the spontaneous reaction.)
Propane, C3H8, when used as a fuel, reacts with oxygen gas to produce carbon dioxide and water. What mass of oxygen will be required to react with exactly 14.05 grams of propane?
Calculate the average translational kinetic energy (sometimes just called average kinetic energy)
The X compound decolors in Bromine, bubbles in Na metal, changes from orange to green in Chromic Acid, and has no reaction with Lucas reagents.
Uric acid dissociates as shown in the figure at the right with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range.
Determine the half-life for the reaction in Part B using the integrated rate law, given that the initial concentration is 1.75molxL^-1 and the rate constant is 0.0020 molxL^-1x s^-1 .
