This is a lab question, referring to zinc and iodine reacting to form zinc iodide.  If at the end of the reaction some of the unreacted zinc escaped from the evaporating dish, the mass of the dish plus the unreacted zinc would be lower than it should be. Would this cause the calculated mass ratio, g I/g Zn, to be higher or lower than the value predicted? I think higher, am I correct? Why or why not?
