Instructions: You may discuss the problems with anyone but the final work should be done independently. Respond to each question precisely as instructed by the question. For example, if the question says explain one reason only explain one reason even if you know many reasons and if the question asks you to calculate a volume do not give a mass. Be sure to label all numeric answers with the correct units. Use correct English and complete sentences for explanations. Each problem will be marked as accepted or “re-do”. There are no “re-do’s” of “re-do’s”. Re-do’s” are not accepted if an “honest” attempt was not submitted on the original due date. All portions of each problem set must be accepted to receive credit for the entire set. When submitting a problem set be sure to indicate the problem set number and if the submission is a “re-do” in the upper right corner.
