The standard free energy deltaG0 for the alcohol dehydrogenase reaction is 5.5 kcal/mole. Assume that you start with 1.5 x 10^-4 M ethanol and 8 x 10^-4 M NAD+, and run the alcohol deydrogenase reaction in the absence of semicarbazide. Formulas and constants to remember R = 1.98 cal/degree-mole ; Delta G0 = -RT lnKeq. T = 298 degrees K. How much NADH will be produced in the above reaction, assuming that no NADH or acetaldehyde was present initially?
A compound of forumula C14H12 gave a positive Baeyer test and burned with a yellow, sooty flame. Treatment with ozone followed by hydrolysis in the presence of zinc gave formaldehyde as one of the products.
15.0 moles of gas are in a 5.00L tank at 22.2°C. compute the difference in pressure between CH4 and an ideal gas under these circumstances. The van der Waals constants for CH4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
Using a solution of (HOC 2 H 2 )3NHCl, solution in which Kb, ((HOC 2 H 2 )3N) = 5.9 × 10 -7 then determine what is the pH of a 0.010 M triethanolammonium chloride,
Buffering Action of Proteins, We did this experiment in class but I want to see if the results seem reasonable and, if so, why they were not more varied.
a sample of nitrogren gas is collected in a 100 mL container at a pressure of 688 mm Hg and a temperature of 565 degrees C. how many grams of nitrogen gas are present in gas sample?
44.0 mL of 0.140 M and Na2SO4 and 25.0 mL of 0.160 M KCl Indicate the concentration of each ion present ?
The background section describes why you want the bleach to be far in excess of the dye. State how much greater the bleach should be to be considered in large excess. If the due is 1 x 10-5 M how much can the bleach be diluted before you no longer..
Thermochemistry : Comparing Heat Capacity of Bricks and Water, A house is designed to have passive solar energy features. Brickwork incorporated into the interior of the house acts as a heat absorber. Each brick weighs approximately 1.8 kg
What are the atomic orbitals used in the double part of the double bond If the C-C axis of the given molecule is the y axis, and the x axis is up and down in the plane of the paper,?
A 50.0 mL sample of vinegar (density = 1.06 g/mL) was diluted to 500.0 mL. Titration of a 50.0 mL aliquot of this solution required 42.5 mL of 0.0900 M NaOH to reach the end point. Determin the acid content of the vinegar as wt. % acetic acid.
