Diffusion of uric acid in protein solution and binding. uric acid (a) at 37°c is diffusing in an aqueous solution of proteins (p) containing 8.2 g protein/100 ml solution. uric acid binds to the proteins, and over the range of concentrations present, 10 g mol of acid binds to the proteins for every 3.0 g mol of total acid present part transport processes: momentum, heat, and mass in the solution. the diffusivity of uric acid in water is 1.21 x 10 cms and = 0.091 x 10 cm/s
(a) assuming no binding, predict the ratio due only to blockage effects.
(b) assuming blockage plus binding effects, predict the ratio . com- pare this with the experimental value for of 0.616 (c8).
(c) predict the flux in g uric acid/s. cm² for a concentration of acid of 0.05 g/l at point (1) and 0 g/l at point (2) a distance 1.5 μm away.

Abaseball picther can throw a ball at about 90 miles per hour, v = 40 m/s, on solid rock ground. we now put him into space. when he throws the ball, which weighs mb = 0.15 kg moves away from himat the same speed. how long does it take the ball thrown in space to travel the 30 meters to the batter? he weighs mp = 100kg

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
