Question

ts materials with you when you take the quiz. The quiz is open notes/book, three attempts, each attempt is 30 minutes. The purpose of the quiz is to prepare you for lab from a conceptual, procedural and a safety point of view. We work with strong acids and bases as well as expensive glassware. An unprepared student is a safety hazard to themselves as well as to their classmates. You MUST pass the quiz (70.00%) to come to lab. If you have not passed the quiz before lab you will not be able to attend. You need to contact Dr. Fishback as soon as possible to discuss your options. If you do not come to lab and do not have a plan with Dr. Fishback you will get a zero for the lab.
