Consider ethanal (acetylaldehyde) which can exist as a pair of tautomers in equilibrium. Calculate the SCF energies of keto and enol forms, convert to Kcal/mole and calculate their relative energy values.
Do the same for 2,2 difluoro ethanal and compare your results. How does the presence of the fluorine atoms effect the keto/enol ratio?
Explain your results thoroughly.
Next do the same for 2 nitro ethanal NO2-CH2-CHO.
What is the sum of the simplest whole number ratio coefficients in the balanced chemical equation for complete combustion of C3H8.
The buret is filled with the NaOH titrant and the initial volume reading is immediately recorded without waiting the recommended 10-15 seconds.
A collapsed balloon is filled with He to a volume of 11.2L at a pressure of 1.00 atm. Oxygen (O2) is then assed so that the final volume of the ballon is 21

Calculate the volume of water required to reconstitute (also referred to as solubilize) the entire contents of the vial of ovalbumin to a final concentration of 6.1 mM.
A sample of gas originally at 37.2oC and 1.25 atm pressure in a 3.4 L container is allowed to expand until the pressure is 0.73 atm and the temperature is 14.9oC.
Demonstrate how an addition reaction of H3O+ to an alkene is the reverse of a catalyzed E1 reaction of an alcohol.
The temperature of a 22.0 g sample of material increases from 190.0 degree C to 42.0 degree C when it absorbs 5.00 kJ of energy as heat. What is the specific heat of this material?
Compute the mass of salt required to bring the freezing point of 200 mL of H 2 O from 0 degrees C to -5 degrees C.
A piece of sodium metal reacts completely with water as follows. 2 Na(s) + 2 H2O(l) 2 NaOH(aq) + H2(g) The hydrogen gas generated is collected over water
