Welcome to Vol. 4 - Chemistry
Here are two links you can use for finding out information you'll need for answering the following set of questions. This whole unit is worth a total of 20 points. This unit's questions can be answered by using the link provided above each set of questions. All assignments must have BOTH the QUESTIONS and the ANSWERS. You can either e-mail me your SPELL CHECKED answers, or turn them in to your class's in-box in my room. Make sure that you have read over your answers SEVERAL times. Misspelled words will NOT be counted.
