Directions: Assign oxidation numbers to all atoms in the following equations, write each half reaction, and then identify which element is oxidized and which is reduced.
Al + Cu+2→ Al+3 + Cu
Oxidized:
Reduced:
Oxidized half-reaction:
Reduced half-reaction:

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".
