Calculate the limiting current for the hydrogen half-reaction, h+(aq) + e- = (1/2) h2(g), which takes place at an rde in hcl(aq) solution with ph=4 at 25 oc and 1 bar (latex: \nu ν = 10-6 m2/s), at an angular velocity of 100 rad/s. the diffusion coefficient of proton can be found in chapter 10: data section.

What pressure will be exerted by 0.675 moles of a gas at 25*c if it is in a 0.750-l container?

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

Which of these best describes an ionic bond?
