You perform a Diels-Alder reaction using 2.0 g butadiene sulfone (MW=118.15 g/mol), 1.2 g maleic anhydride (MW=98.06 g/mol) and 0.8 mL xylenes (MW=318.5 g/mol, density=0.862 g/mL). What is the theoretical yield of the reaction?
The titration of a 50.0 mL solution of the monoprotic bromoacetic acid (pKa = 3) takes 10 ml of 0.01 mol L-1 NaOH to reach the stoichiometric point. What was the initial concentration of bromoacetic acid?
A bullet of mass 45 g is shot at a speed of 220 m/s into a 5.0-kg bag hanging from a string from the ceiling. The bag absorbs the bullet and begins to swing. To what maximum vertical height will it rise?
