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. Make a list of the names and formulas of all of the compounds we have discussed in class in this unit, and where they are found.

5. Look through the Unit 3 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.

6. Do the Exam 3 Review Questions in class or print them out from the course website. Look at the key to make sure you understand these concepts.

7. 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 (you will not be able to choose which one). You should be prepared to write a good, clear essay (1/2 to 3/4 page) about each one. Be sure to answer all parts of the question in your essay.

1. Explain why metal is vital to our society, giving at least 4 examples of things that we would have to go without in a world without metal. Then explain the difference between metal smelting and metal corrosion. What other chemicals participate in these reactions? In which case are the metal atoms losing electrons, and in which are they gaining electrons? Why does one happen naturally, while the other does not?

2. Explain how a knowledge of acids and bases can help when cleaning your house. What types of cleaning jobs require acids, and which bases (things like cleaning floors, dishes, ovens, toilet bowls, sinks, windows, and tubs)? Name some household chemicals that would be good for cleaning if you didn't have an commercial cleaning products. What dangers can come from mixing cleaning solutions?

3. The 20th century has been called the plastic age. Discuss in detail the pros and cons this versatile type of material. List at least 4 properties that make it useful.
