Student Outcomes: 1. Use conversion factors as a tool for manipulating units. 2. Generate conversion factors from available information. 3. Recognize patterns in problem solving and develop a procedure to describe the process. 4. Perform calculations and determine whether the answer is reasonable. 5. Use chemical vocabulary appropriately. 6. Distinguish between ionic and covalent compounds. 7. Name chemical compounds including acids. 8. Write chemical formulas from names. 9. Write and balance chemical equations. 10. Describe how the principles of solubility are used in identifying ions in solutions. 11. Calculate concentrations of solutions including molarity, molality, percent, and ppm and perform interconversions between units. 12. Prepare solutions of appropriate concentrations using solid and stock solutions. 13. Write molecular and net ionic equations. 14. Predict the products of precipitation and acid/base reactions. 15. Predict chemical formulas using ionic charges and empirical formulas. 16. Perform stoichiometric calculations including limiting reactant, percent yield and solution stoichiometry. 17. Use the kinetic molecular theory to describe gaseous behavior and the gas laws. 18. Apply the gas laws in calculations. 19. Explain the limitations of the ideal gas and the usefulness of van der Waal s equation. 20. Recognize when a reaction is exothermic or endothermic with respect to enthalpy and the direction of heat flow. 21. Recognize and describe the difference between a state function and a non-state function. 22. Perform calculations based on Hess s law. 23. Measure heat of reactions.

2 24. Design and perform experiments. 25. Demonstrate the appropriate use of standard laboratory equipment. 26. Practice standard laboratory safety precautions. 27. Use chemical reference materials appropriately. 28. Use computers to gather and analyze data. 29. Communicate the results of laboratory work. Prerequisite: Chem 139 or one-year of high school chemistry and Math 141 (which may be taken concurrently) or instructor s permission. How to succeed in this class: The key to success in this class is to keep up with the material and do lots of practice problems. I will assign homework every class period. It is your responsibility to do this work to the best of your ability. During the next class meeting some time will be devoted to answering questions from the previous day s assignment. New chapters will build on previous knowledge and incorporate concepts from earlier chapters. It can be easy to get behind so it is important to be sure you fully understand the material at each step along the way. There will also be online homework assignments for each chapter on Sapling. Group Work and Quizzes: There will be three group work assignments given during the quarter. You must be present in class to attempt the assignment. Working in small groups encourages good study skills which you will find to be valuable, not only in this course, but in future courses. Quizzes will also be given throughout the quarter. No make up group works or quizzes will be given, but the lowest score will be dropped. Homework Groups: You will be discussing and checking homework every day with a group of 3-4 students. I will be handing out a grading sheet to each of the groups and you are responsible for honestly evaluating your effort. I will collect the homework periodically and if you have not evaluated you work honestly, you will receive a zero for that day s work. You must arrive in class on time to get full credit, and if you are going to be absent, you must discuss your reason with me before the class for the absence to be excused. If, after discussing the homework with all of your group members, you still have a question about a problem, I will work the problem for the class. Lab Notebook: You must have a bound laboratory notebook for this course. In this notebook you will prepare for lab each week by writing the Title, Date, Purpose and a short (4-5 sentences) overview of the procedure. I will check your notebook at the beginning of each lab period. If you are late for lab you will not receive the points for the prelab. If you are more than 10 minutes late for lab you will not be able to participate in the lab and will receive no credit for that day s lab. You will write (using a ballpoint pen only) all observations and measurements made in lab in this notebook. After each lab you should write a brief conclusion which addresses how well the lab met the purpose you had outlined in the prelab. A copy of your lab notebook must be turned in with your lab report. Lab Apparel: You must wear long pants or a long skirt to lab and also wear closed toed shoes. If you are not wearing appropriate clothing you will not be allowed to work in the lab and will receive no credit for that day s lab. You must wear safety goggles which will be provided in the lab and will be sterilized after each use. Lab Reports: There is a lab report to be filled for every lab which can be found on the Canvas website. The lab report is due at the beginning of lab the next week unless otherwise specified on the schedule. You may choose to do the lab report on your own or with your lab partner. If you choose to work with your partner on the lab report, the work must be shared equally. Late lab reports will lose one point per day late and cannot be turned in after they have been returned to the rest of the class.

3 Course Grading: Your overall grade will be determined from a total of 750 possible points as follows: Midterm Exams Quizzes and Group Work (the lowest score will be dropped) Homework Sapling Online Homework Lab Reports and Lab Notebook Comprehensive Final Exam 300 points 100 points 50 points 50 points 150 points 100 points Your final grade will be based upon your percentage of total possible points as follows: Percentage Grade Percentage Grade % % % % % % % % % % % % % % % 2.6 Below 60% % 2.4 Cell Phones: The use of cell phones is prohibited during class time. This includes conversations, texting, browsing, etc. It is a distraction not only to you but to other students. If I see your cell phone at any time during a quiz or an exam you will receive a zero for that assignment. There will be no exceptions to this policy. Academic Integrity: It is expected that all students will follow the Pierce College Student handbook policies corresponding to academic dishonesty and the consequences of violating those policies. NOTE: Sharing of any resources (such as, but not limited to, calculators, notes, information, ) during exams or quizzes is prohibited and will result in a zero on that assignment. Missed Exams and Labs: No makeup exams, quizzes or labs will be given. The lowest lab grade will be dropped so you can miss one lab without it affecting your grade. If you must miss an exam for an unavoidable reason (this does not include vacations or doctor s appointments), you must discuss your situation with me before the exam was scheduled about the possibility of taking it at another time. Regrading of Exams: If you would like your exam to be regraded, it must be given back to me within 48 hours of its return to you along with a note explaining what you want reconsidered.

If you experience barriers based on disability, please seek a meeting with the Access and Disability Services (ADS) manager to discuss and address them. If you have already established accommodations with the ADS manager, please bring your approved accommodations (green sheet) to me at your earliest convenience so we can discuss your needs in this course. ADS offers resources and coordinates reasonable accommodations for students with disabilities. Reasonable accommodations are established through an interactive process between you and the ADS manager, and I am available to help facilitate them in this class. If you have not yet established services through ADS, but have a temporary or permanent disability that requires accommodations (this can include but not be limited to; mental health, attention-related, learning, vision, hearing, physical or health impacts), you are encouraged to contact ADS at (Fort Steilacoom) or (Puyallup). Emergency Procedures for Classrooms: Call 911 and then Campus Safety in response to an imminent threat
