Make a sketch of a concentration cell employing two Zn/2+ half-cells. The concentration of 2+ in one of the half-cells is 2.0M and the concentration in the other half-cell is 1.0x10−3M. Label the anode and the cathode and indicate the halfreaction occurring at each electrode. Also indicate the di-rection of electron flow.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
