Construct a three-step synthesis of trans-2-pentene from acetylene by dragging the appropriate formulas into the bins. note that each bin will hold only one item, and not all of the given reagents or structures will be used. (me = methyl, ch3; et = ethyl, ch3ch2.)'

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".
