A gas obeys the van der Waals equation of state. The critical parameters for this gas are Pc=47.7 atm, Tc=151.15K, and Vc=0.0752 liter mol^-1. Evaluate the reduced pressure of the gas at 300K and a volume of 15 liters.
Consider the galvanic cell with Sn2+/Sn and Ag+/Ag both prepared with NO3- as their anion and all solutions prepared at 1.0 M. What is the reduction half-reaction and does it occur at the anode or cathode? Also..what is the standard cell potential
Provide structures of the two allylic free radical intermediates in this reaction. b. Provide structures of the two substitution products in this reaction. c. Identify and circle the major product in (b) above.
If we assume that the atmosphere of the earth is an ideal gas mixture, then each component is described by a separate barometric equation. This model predicts that the concentrations of heavier molecules, and therefore their partial pressures, dec..
Calculate and plot the points where 0.00, 5.00, 10.00, 20.00, 25.00, 30.00, 35.00, 40.00, 45.00, and 50.00 mL of 0.075M KOH has been added
A compound is 80.0% carbon and 20.0% hydrogen by mass. Assume a 100.- sample of this compound. How many grams of each element are in this sample
the pH of the two equivalence points and the volume
sketch the full schematic for the voltic cell corresponding to the redox reaction shown below;Fe(s) +Cu^2+(aq)---->Cu(s)+Fe^2+(aq). write the shorthand notation for the voltic cell corresponding to the above redox reaction.
The atmospheric activity of 14 C is 15 cpm/gC (counts per minute per gram of carbon). Assume that the cloth was made in the year 24 B.C. The half-life of 14 C is 5730 years. What will be the expected activity of 14 C of this sample
Which of the alkaline earth metal hydroxides, M(OH)2, would you expect to be most soluble in water? Least soluable?
