The Midterm is a combination of five parts. There will be 50 multiple choice
including calculations, 16 matching, 20 true/false, 14 on reading a diagram, and 5
essays.
•
You will need to bring a pencil to the exam for the scantron section and a pen for
the rest of the exam. You will also need to have with you a calculator for the
calculation section.
•
You will be given a periodic table and also a ion chart.
•
Talking will not be allowed at any time during the exam.
