Review Sheet - Exam 1 - CH301 - McCord Which Chapter/Sections are covered? Chapters 1-4, the “Fundamentals” were covered on homeworks 1 and 2 (not to mention, ALEKS). I DO plan on asking at least ONE question from the fundamentals (stoichiometry most likely), however, the exam is based on content in Chapter 12 . All the material on the exam has been covered in one way or another on homeworks 3 and 4 and my lectures. Concentrate on the subject matter emphasized in class and on these homeworks. If I didn't cover it in class, it will NOT be on the exam. Come in mentally prepared to answer at least 25 questions, maybe a few more. Yes, there will be calculations, but most of the questions will be over theory and concepts. You need to understand the theory and concepts to the level at which we studied it. I don’t expect you to solve the Schrödinger equation, but I do think you should understand what it meant towards modern atomic theory. And, just because you got a homework question right does not necessarily mean you really understand the material. Try explaining the concepts to someone else to see if you really understand. Bring a pencil(s) and non-graphing calculator to the exam. WE will provide you with an exam copy, an answer sheet (bubblesheet), and any scratch paper that you might need. I was going to have you memorize formulas, like 3 or 4 of them, but then I decided to just print them on the exam anyway. Formulas will be on the exam as well as ALL constant needed in the formulas. There might even be some extra constants and formulas, so just use the necessary formulas and constants. Energy traveling at the speed of light Know what electromagnetic radiation is and how we depict it on the page and conceptually. Know the basics of the entire electromagnetic spectrum (Figure 12.3 in your book is much like the one shown here which I grabbed off the internet).

Know the approximate wavelengths for each type of radiation given (LOOK at that figure). Know also, that visible light is in the 400-700 nm range (that’s blue end to red end). Other than the two ends, I do not expect you to know the wavelengths of all the colors of the rainbow – however, you SHOULD know the ordering of the colors (think Roy G. Biv). Use Your Resources - the Internet Type in “electromagnetic radiation” into a google image search. LOTS of good pictures for learning the relative areas of the scale. Do know what type of excitations go with the various radiation types. For example, visible and UV light yield electronic excitations in atoms and molecules while infra-red (IR) radiation really just causes vibrational excitations. The internet is your friend - use it and you can find countless examples of ALL of this material.
