A sample of magnesium metal was placed in a solution of hydrochloric acid producing magnesium chloride and hydrogen gas. The hydrogen was collected by water displacement at 25.0oC and found to have a total pressure of 1.10atm and a volume of 2.00L. If the vapor pressure of water at 25.0oC is 0.03126 atm, how many grams of magnesium were used in the reaction?

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.
