A sophomore chemistry student holds a 500mL Erlenmeyer flask full of concentrated nitric acid high above his head at a height of 1.75 meters and declares, "I'm the King of Chemistry!" At that moment another student, startled by the sudden ignition of her Bunsen burner, jumps back and bumps into the King, who drops the flask. How long until the flask breaks all over his royal sneakers?
