If a 22.5 mM copper (II) solution(solution A) had an absorbance of 1.065. What would be the absorbance if 8 mL of solution A was used to prepare a 20.0 mL of a new copper (II) solution.

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.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
