Estimate the diffusion coefficient for methyl phenyl sulfide in water at 25 degrees Celcius.
15. What is the diffusion coefficient (m/s) in water at 25°C of a bovine pancreas ribonuclease (an enzyme that digests RNA) whose molecular weight is 1.369x109 and which is spherical?, Assuming the protein is an unhydrated sphere and its density is 1.414 g/cm'. The viscosity of water is 10- Pas. [Hint: Calculate the radius of the protein and use the Einstein relation to estimate the diffusion coefficient.] (10 pts)
0.00490 grams of baso4 dissolved in 2.0 liters of water at 25 degrees celcius calculate ksp for baso4
an iron cylinder with a mass of 25.0g at 105 degrees celcius is placed in a beaker containing 25.0 ml of water at 25 degrees celcius. Assuming that no heat is lost to the surroundings, what will the final temperature of the water bne? the specific heat capacity of iron = .449 j/g degrees celcius and water = 4.18
If you combine 350.0 mL of water at 25.00 degrees Celcius and 130.0 mL of water at 95.00 degrees Celcius, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.
The volume of SO2 collected by water displacement at 18 degrees celcius and 1500 mmHg is 5 L. What is the volume at 35 degrees celcius and standard pressure?
To make ice water, I mix 200 g of water at 25.0 degrees celcius with 100 g of ice cubes at -15.0 degrees celcius. Water density is 1.00 g/cm^3, and the container perfectly insulates the system from the enviroment. Thermal equilibrium is eventually reached. Assume that all the ice must reach 0 degress celcius before any ice begins to melt. (a) determine (i) if any unmelted ice remains, and if so, the mass of the remaining unmeltd ice, and (ii)...
