Explain Lysozyme is an enzyme that cleaves bacterial cells walls. A sample of lysozome extract from chicken egg white has a molar mass of 13,930g. Explain a quantity of 0.1g of this enzyme is dissolved in 150g of water at 25 degrees Celsius. Compute the vapor pressure lowering, the depression in freeing point the elevation of boiling point, and the osmotic pressure of this solution. The vapor pressure of water at 25 degrees Celsius is 23.76 mm Hg. Kf(H2O)= 1.86oC/m. KB(H2O)= 0.5286oC/m
What is the molarity of a solution prepared by dissolving 5.72 grams of NaOH in 43.8 ml of solution. What is the balanced equation for the reaction of sodium hydroxide with sulfuric acid. How many ml of 0.101 M H2SO4 solution would be required to ..
For the concentration of hydroxyl radical of 7.5E06 molecules/cm3 and a carbon monoxide concentration of 18 ppm, calculate the rate of its reaction with atmospheric carbon monoxide at 11 degrees C.
Assume that the vapors and solutions are ideal. Calculate the composition (mol% each component) of the condensed liquid. What is the vapor pressure of pure toluene at 94.8°C
a half-cell that consists of a copper wire in 1.00 m cuno3 solution is connected by a salt bridge to a half cell
you add 7ml of 6m naoh to a flask and diluted with water to a final volume of 400ml with water. neutralization required
The formula for the illegal drug cocaine is C17H21NO4. What is the percentage of hydrogen in the compound?
The quantity of antimony in an ore can be determined by an oxidation - reduction titration with an oxidizing agent. The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all the antimony
We are unable to detect iron via atomic spectroscopy. The problem is we have added Fe-EDTA in a formulation. For detection of Fe, we digest the formulation (sample) with H2SO4 (usual practice) but we are unable to detect Fe by atomic spectroscopy.
Calculate the pH of 100 mL of .30 M NH3 before and after the addition of 4.0 g of NH4NO3 and account for the change. assume the volume remains constant
At 699 K, deltaG = -23.25 kJ for the reaction H2(g) + I2(g) --> 2HI(g). Calculate deltaG for this reaction if the reagents are both supplied at 5.0 atm pressure and the product is at 1.00 atm pressure.
