Given that translational and rotational degrees of freedom typically behave classically, but vibrations behave quantum mechanically, the total (avg) energy of a diatomic is predicted to be U= (5/2)RT+<e>, where <e> is obtained from Eq.124.
A. Verify the first equality in R (beta(delta e)^2e^Beta(delta e)/[e^Beta(delta e)-1]^2 using the chain rule, and then verify the second equality in the same bolded equation by evaluating the derivative with respect to Beta(and then manipulating the result to show that it is equivalent to the final expression).?
B. Use Cv/R= 5/2+ (beta(delta e)^2e^beta(delta e)/[e^beta(delta e)-1]^2 to predict the molar heat capacity of Cl2 gas at 300 K, using the information provided in problem 9, above, and compare your result with the experimental molar heat capacity of cl2, cv~ 26 J/(kmol) at 300 K?
A 335 mL container holds 0.146 g of Ne and an unknown amount of Ar at 35°C and a total pressure of 628 mmHg. Calculate the moles of Ar present.
Would applying a high pressure stabilize the CsCl form, or the NaCl form of this compound? (hint: calculate the volume per formula unit)
Draw the major product for each of the following reactions. Make sure that you draw a major product that could be isolated, not just an intermediate or something that would be present only in low equilibrium population.
Based upon what you know about acids and bases, and given that manganese will be reduced by sodium bisulfite, make a prediction about how the oxidation-reduction reaction will be affected by acidic
A1.15 g sample of dry ice is added to a 765 mL flask containing nitrogen gas at a temperature of 25.0 C and a pressure of 715 mm Hg.
Draw the major organic product(s) formed when hex-2-yne undergoes hydration in the presence of HgSO4 and H2SO4.
NMR of D exhibits resonance at -4 ppm. - On heating D, a flammable gas and A are formed. - Reaction of C with CH3I affords white solid E whose proton NMR shows a single resonance around 0.2 ppm. Identify A-E.
Dipole moment, Formaldehyde has a very large dipole moment (2.33 Debye) whereas carbon monoxide has a very small dipole moment (0.11 Debye)
What is the molar mass of the gas in a glass bulb with a volume of 2.50 L at a temperature of 22 degrees C and a pressure of 110 mm Hg. The gas weighed 505 mg.
This experiment calls for the use of 2mL of 2-chloro-2methylpropane. The molar mass of 2-chloro-2methylpropane is 92.57g mol-1, and its density is 0.847g mL-1. 1) Calculate the number of moles of 2-chloro-2methylpropane used in this experiment.
