Lectures MTW 11 11:50 am, APH 101 Conference Th 11 11:50 am, APH 101 Conferences will be a mix of additional lecture material, review, and exams/quizzes. It is required! Prerequisite A grade of C or better in MATH 093/095, or equivalent, or consent of the instructional unit. Textbooks, Materials and Resources Introductory Chemistry (2 nd ed.), Nivaldo Tro (ISBN ) The text is required! Because of the abbreviated nature of the course, you will be responsible for reading the text, working through examples and suggested problems. You can use either the regular text, or the custom publish half-text that is available in the bookstore. A non-programmable scientific calculator (logs, scientific notation). This is the only type of calculator that may be used on exams. It is Chemistry Department policy that no programmable calculators (eg TI-8X, HP) may be used during exams. A good calculator is the TI-30X, which is typically around $ Bring your calculator to class with you every day! Please get into the habit of checking the CHEM 100 portion of my website regularly! Lecture announcements and suggested problems will be posted there, along with pdf s of all homework assignments, answer keys, review sheets, guides, and anything else I can find/create that is useful. There will also be useful links to other review sites. NOTE: You will need a current version of Acrobat Reader to be able to download the material and see all of the figures! World of Chemistry videos, available at the library. These provide an alternate and visual explanation of some of the course materials. Course Overview CHEM 100 is a preparatory class for the CHEM general inorganic chemistry sequence. The sequence is designed for Chemistry majors, other science majors, or anyone intending to pursue an advanced degree in the sciences, health fields or engineering. The sequence covers a wide breadth of topics designed to teach the language of chemistry. This course gives a foundation that can be used throughout the sequence, but primarily to prepare you for CHEM 131. Upon completion of this course, you should feel more than prepared to successfully enter the CHEM series and succeed! Lecture Course Objectives (linked to the College-Wide Abilities): Develop critical-thinking skills required to analyze problems and determine outcomes. (Problem solving, Critical Thinking) Analyze information from different sources to solve problems. (Problem Solving, Critical Thinking, Information Technology, Communication, Lifelong Learning) Use dimensional analysis to devise a solution plan; use the unit-factor method of problem solving. (Problem Solving, Critical Thinking) CHEM 100 Syllabus Fall 2007 Page 1 of 6

2 Use proper measurements, units, and significant figures when solving problems (Problem Solving, Communication, Critical Thinking) Define the various states of matter and the different types of composition and change (Problem solving, Communication, Critical Thinking) Understand the nature of atomic structure, elements, ions and isotopes (Problem Solving, Critical Thinking, Communication) Use standard IUPAC nomenclature to name inorganic salts, and binary compounds. (Problem Solving, Critical Thinking, Communication) Develop methods to determine amounts of compounds, chemical compositions, and reaction yields. (Problem Solving, Critical Thinking, Communication) Write and balance chemical equations. (Problem Solving, Critical Thinking, Communication, Life-Long Learning) Understand how electrons, atoms and molecules are theoretically organized. (Critical Thinking) Represent molecules three-dimensionally on paper, account for the location of electrons within a compound. (Problem Solving, Critical Thinking, Communication, Information Technology). Communicate these ideas on paper (homework, quizzes, exams) and verbally (group work), collaborate as a team. (Communication, Information Technology) Chapters we will cover (in some part) this quarter: Ch. 1 The Chemical World. Ch. 2 Measurement and Problem-Solving. Ch. 3 Matter and Energy. Ch. 4 Atoms and Elements. Ch. 5 Molecules and Compounds. Ch. 6 Chemical Composition. Ch. 7 Chemical Reactions. Ch. 8 Quantities in Chemical Reactions. Ch. 9 Electrons in Atoms and the Periodic Table. Ch. 10 Chemical Bonding. Specific Chapter Objectives and suggested problems will be given in class or on the course website look for them! Course Expectations and Strategies for Success- Student Because of the amount of information presented and the short time frame of this course, the material will be presented at a fast pace. It is imperative that you keep up with the pace of the course! Attending lectures and conference, reading the text and working through suggested and homework problems throughout the week will all contribute to your success in the course. I expect each student to participate in lecture by answering and asking appropriate questions and working through in-class exercises. I also expect each person to spend AT LEAST 10 hours outside of lecture and conference working on material. Chemistry is best learned in small, repetitive bites (chew a lot, then swallow) you are better off spending 1 hour per day than 5 all at once on a weekend. Your time outside of class is best spent on the following activities. The following suggestions will help you keep up: 1) Read the assigned material before coming to class. Keep a notebook and sticky notes near by to work through problems, flag questions, and make notes. 2) Recopy your lecture notes from one class before the next class it will help identify questions and clarifications. 3) You need to have web access for this course. If you do not have access at home, there are several computer labs available on campus for student use, but require a student log-in. Labs on campus are open at various times Mon Sat, and some open as early as 7:30 am and close as late as 8 pm. More information about computing resources for students can be found at 4) Do the suggested problems! They are a good source of practice material (repetition!). You may even see a suggested problem on an exam. CHEM 100 Syllabus Fall 2007 Page 2 of 6

3 5) Get help promptly. Find a study buddy, find a tutor, find me! The tutoring center ( ) is now located in Hawkins 102/103. 6) If any questions pop up while doing any of the above study techniques, please them to me! I can and do respond to s fairly quickly, or if I get several s on a particular problem/topic, I can address it in class the next day. Course Expectations - Instructor In return, you can expect that I will also keep pace with the course (I am a procrastinator by flaw ). Classtime will be a mixture of lecture and both group and individual practice. You are welcome to tape lectures. Assignments will be posted on schedule, and graded assignments will be returned within two days (usually faster). Answer keys and study guides will be posted to the course web promptly. Exams will cover the material fairly there should be no surprises, but there will be challenging material! I have taught the CHEM sequence several times, and I view this class as my opportunity to prepare students as I wanted them prepared for my CHEM 131 class. MOST IMPORTANTLY, I am available to meet with you on a one-on-one basis for assistance with any aspect of the course or your studies. Please use me for this! Course Policies Withdrawal Policy and Registration Deadlines Students will be allowed to drop a class, without instructor signature, through the seventh week of the quarter (or after 70% of the course is complete). Students who drop after the 10th day of the quarter receive a 'W' grade on their transcript, which does not affect their GPA. No drops will be allowed after the seventh week. Students who feel they have extenuating circumstances may appeal this policy by contacting the unit dean before the end of the last scheduled day of the quarter (before finals). Important Dates: Spetember 28 Last day to drop online, last day for a 100% refund. October 5 Last day to drop without a W. November 9 Last day to drop the course!!! Students with Disabilities If you have a disability and/or need an accommodation during class or for exams, please make arrangements to meet with me outside of class to discuss your specific request. A request for accommodation will require that documentation of the disability be reviewed by Disability Support Services (DSS). DSS can be contacted at ( TTY), or you may go to their offices located in the Penguin Union Building (PUB 014). Information can be found through the Clark Web: Academic Honesty The scientific community is built upon collaboration with ones peers for support and guidance. I encourage you to work with other students and collaborate with each other for assistance. However, the work to be done in lectures, recitations and at home must be your own work, written in your own words. You should always be prepared to explain the rationale behind your work. Any cheating incidents will handled on a case-by-case basis and may result in a zero on the assignment or in the course, or removal from the class or the college, as defined in the Student Code of Conduct. The Code can be found at or can be obtained from the Office of the Vice President of Student Development (x2103). CHEM 100 Syllabus Fall 2007 Page 3 of 6

4 Absences, Make-ups and Late Assignments Attendance and punctuality to the lectures are essential for success in this class, and demonstrate a Life-long Learning Skill. Each student is expected to attend lectures as scheduled. I do not lecture from the book! The lectures are designed to provide an alternate explanation of the materials in the text and an opportunity to practice the material and ask questions with the instructor present. I often focus my graded assignments and exams to work done in class you are responsible for any material covered in class, and it is extremely important that you attend lectures! We will have daily homework assignments through the course, and homework is due at the beginning of class. Therefore no late homeworks will be accepted! The grading policy, detailed below, is designed to allow for an occasional missed homework assignment. In general, there are no Make-up Exams, without prior approval. Extenuating circumstances can be handled on a case-by-case basis, provided that you contact me promptly, and (at lease one day) before the absence. I am pretty flexible, I just don t like surprises and like to know ahead of time! If you have a question or concern about a graded assignment, and how it was graded, please come and see me outside of class time. Cell Phones Please turn your cell phones completely off during class and conference. A cell phone on vibrate against a tile floor makes a very interesting mooing sound! Campus Emergencies In emergencies, students should do the following: 1. Inclement weather or emergency information Go to or call as your first means of getting information. The College does send notices to radio and television stations, but the College s web site and switchboard are the official platforms for the most accurate information. 2. Immediate emergency communication alert To receive immediate notice on emergencies, you can register your cell phone number to receive text pages and your address to receive messages. To do this, go to Select Subscribe on the left, and follow the instructions. Mass communication will also be sent to all college employee phones and computers. 3. Fire Alarm Evacuate the building through closest exit; evacuation maps are located in the hallways. Take personal belongings only if it is safe to do so. Remain at least 50 feet from the building. Notify others of evacuation. Do not re-enter building until instructed to do so. 4. Parking Lot Identifiers New parking lot identifiers using colors and numbers have been assigned to all Clark parking lots. To help emergency or security personnel locate you, please refer to these identifying features. 5. Security Escort Security Officers are available for escorts please call CHEM 100 Syllabus Fall 2007 Page 4 of 6

5 Grading and Assignments Throughout the term, you will be expected to complete a series of assignments, all of which will be created by me. They are detailed below, along with the grading scheme for the course. Homework and Activities 25% There will be biweekly homework assignments, due on Tuesdays and Thursdays. Exceptions may occur during exam weeks. Each assignment will be worth 5 points. You will be able to drop the score of your lowest homework assignment; if you choose to skip an assignment, that zero score will be dropped. Homework assignments will be posted to the class website and announced in class as well. The answer keys will be posted to the website after the assignments are due and before the next class. The assignments will all be problems that I write, and are not taken from the suggested problems given. Each assignment will typically be 3-5 problems in length, with many problems containing multiple steps. Some additional assignments may be in-class activities, or web-based activities. Do not skip homework assignments! They are very representative of exam questions. Homework assignments need to follow a certain format. More details on the next page! Exams 45% There will be three, 50-minute exams during the quarter, tentative dates and material covered are listed on the calendar. The exams will be a mixture of show-your-work problems and multiple choice. The exams will not necessarily be cumulative, however the material builds on itself and you will be responsible for that knowledge. You will be able to replace your lowest exam score with the score on the final, if it is higher. Final 30% The final will be cumulative, and will focus on combining skills you have learned throughout the course. You will be able to replace your lowest exam score with the score on the final, if it is higher. To determine your grade: [Hwk Avg x 0.25] + [Exam Avg x 0.45] + [Final x 0.30] = Grade % A % B % C % D % F <60.0% Homework Policy and Format I reserve the right to lower the cut-offs of this grading scale. Anyone near a grade boundary will be considered on an individual basis. Minus grades will be given to the bottom 2% of each grade, plus grades will be given to the top 2% of each grade, except A+. Homework problems represent only a small portion (the bare minimum) of the number of problems you are expected to work. It is the responsibility of the student to know if he/she understands the material. NO LATE HOMEWORK IS ACCEPTED. Homework is normally due at the beginning of the next class period after it is assigned. In order to receive credit for the homework assignments, they must be written in the proper format this makes it easier for me to grade them, and return them faster to you. You will be able to drop your 2 lowest homework scores. Homework is due at the beginning of class, on the due date. Once lecture has started, I will deduct 2 points from the homework score. I will not accept homework placed in my box after the start of class. The answer key will go up shortly after class, on the course website. CHEM 100 Syllabus Fall 2007 Page 5 of 6

6 HOMEWORK FORMAT 1. Write your name and class in the upper right hand corner of a standard 8.5 x 11" sheet of paper (lined or unlined). Engineering graph paper is fine. If you have multiple pages, please staple (not fold) and number them. Put your name on each page. Personal pet peeve please cut off the fringe from spiral-bound notebook paper! 2. Rewrite the problem/question. You may summarize or use abbreviations but the question and given data must be clear. You may type them out if you wish. You may also cut the assignment sheet and tape it on your homework. 3. List the relevant formula used in the problem, if applicable. 4. Show all work using dimensional analysis with proper units. 5. Place answers (with correct significant figures and units) are boxed or highlighted at the end of the problem. 6. Papers are neat and legible. If I cannot read it, I will not grade it. Example: 1. Determine the color of the sky, given a typical transition energy of 3.75 x J.!E = h" = hc # 3.75 x J = # = 5.30 x 10-7 m 5.3 x 10-7 m x ( x J$ s) ( x 10 8 m/s) # 1 nm 10-9 m = 530 nm % Blue The Sky is blue CHEM 100 Syllabus Fall 2007 Page 6 of 6
