Information about Exam 1

About the Exam

The exam will be given Tues, Sep 13 – Wed, Sep 14 in the Testing Center. Bring a scantron sheet (available in the bookstore) and your Dixie College ID with you, and make sure you can tell them my name (Sarah Black) and the class (Chem 1010, sec 2). You have an unlimited amount of time to take the exam, so be sure to give yourself plenty of time, and go to the bathroom first! The last exam is given out an hour before closing (9 pm). You should plan on about 2 hours to take the exam.

The testing center hours are:

Tues: 9 am – 10 pm
Wed: 9 am – 10 pm

If you fail to take the test on these days, you may see me for permission to take the exam with a 10% late penalty. If you would like to petition to have this penalty waived because of a personal difficulty, please let me know.

The exam will contain:

A periodic table (just like the one I gave out in class) will be printed on the front of the exam for you to use.



Before you take this exam:

1. Review your Learning Guides, using the posted Lecture Notes on the course website to make sure that you have all of the information. If there is something you are confused about, read that section again carefully, then write down any questions that you'd like to discuss in the Review Session in class. (Note: material from the class discussion will NOT appear on the exam.)

2. Look at the Study Questions on Blackboard. Starting at noon on the first day of the exam, you will be able to see the answers to these questions if you got them wrong. Make sure you understand the correct answer to all of the questions that were asked.

3. Go through each lecture and make a list of key terms and their definitions.

4. Look through the Unit 1 Learning Outcomes given on the course website. This will help you to know what you are supposed to be able to do with the information in each lecture.

5. Do the Exam 1 Review Questions in class or print them out from the course website. Look at the key to make sure you understand these concepts.

6. Look at each of the possible essay questions listed below. Be sure that you can write a thorough essay (1/2 to 3/4 page) on each topic.



Essay questions - One of the essay questions from the list below will appear on your exam (all four will be used on different copies of the exam!). You should be prepared to write a good, clear essay (1/2 to 3/4 page) about each one. I am not looking for you to simply restate what was given in the notes. Please explain in your own words! And be sure to answer all parts of the question in your essay.

1. Explain how Legos and letters can be used to explain the idea of atoms, elements, compounds, and chemical reactions, including how so many substances are possible from only a certain number of building blocks, and how only certain combinations are possible.

2. Explain what periodicity is, and give some examples of things that are and are not periodic. Then explain how periodicity of the elements is used to create the Periodic Table, and why this is better than a list of the elements.

3. Compare pure elements, compounds, and mixtures. What makes each different from the others? What kinds of substances are made of individual atoms, which of molecules, and which of ions? Include examples of actual substances in your explanation.
