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
Calculate the total concentration of lead dissolved ([Pb]total) in a solution saturated with PbI2(s) and containing dissolved I- with a concentration of [I-] = 0.294 M. The solubility of lead is governed by the reactions shown below.
Calculate the mass of nitrogen dissolved at room temperature in an 76.0L home aquarium. Assume a total pressure of 1.0 atm and a mole fraction for nitrogen of 0.78
Predict the outcome of reactions that occur when a solution having [Cu2+]/[Fe2+] = 10 comes in contact with hydrotroilite (FeS). What will be the ratio of [Cu2+]/[Fe2+] in the solution after equilibrium is established?
Butryic Acid is responsible for the odor in rancid butter. A solution of .25M butryic acid has a pH of 2.71. What is the Ka for the acid
Container A holds 727 mL of ideal gas at 2.20 atm. Container B holds 134 mL of ideal gas at 4.20 atm. If the gases are allowed to mix together
The student then adds more water until the solution volume becomes 1.0 L Write the eqn for each large-extent B/L A/B rxn which occurred on making this mixture. Do this by starting with the rxn that involves the strongest B/L A with the strongest B..
At high pressures, Ne behaves as an imperfect gas. In the range 300 K to 500 K the equation of state for one mole of Ne (g) can be written as:
This phenomenon has some very practical applications in the power plants, particularly nuclear power plants. How does this help the overall efficiency of a nuclear power plant?
How many photons will be required to raise the temperature of 2.3 g of water by 2.1k ? Water is exposed to infrared radiation of wavelength 2.7×10?4 cm . Assume that all the radiation is absorbed and converted to heat.
SLIGHTLY LESS than 100 degrees Celsius, but the final boiling point was AT 100 degrees Celsius. Why should the boiling point rise as the distillation progresses?
