1 Chem 305 Fall 2017 Linda Nuss Class Syllabus INTRODUCTION: Chemistry 305 is an introductory course that covers the fundamental principles and concepts of inorganic chemistry. It is intended for students majoring in allied health (nursing, dental hygiene, physical therapy assistant, etc.), environmental studies, or physical education. Chem 305 also satisfies the GE lab science requirement for California transfer institutions. Part of the Chemistry 305 experience is learning about and getting used to the culture and expectations associated with science courses. The following material is a list of some of the requirements of the course to help you be well prepared. INSTRUCTOR CONTACT INFORMATION: Lecture and lab: Linda M. Nuss Office: Lillard Hall Rm 202D nussl@scc.losrios.edu Phone: (916) Science office phone ( ) for emergencies Web Page: COURSE DESCRIPTION This is course presents the fundamental principles of chemistry including types of matter, physical and chemical processes, chemical bonds, atomic and molecular structure, nuclear chemistry, stoichiometry, states of matter, intermolecular forces, solutions, types of chemical reactions, acids and bases, equilibrium, and a brief introduction to organic chemistry. It is primarily designed for majors in the allied health fields (nursing, dental hygiene, physical therapy, etc.), natural resources, environmental technology, and physical education. Online homework assignments may be required. STUDENT LEARNING OBJECTIVES Upon completion of this course, the student will be able to: demonstrate a knowledge of introductory chemical concepts. relate chemistry to applications in everyday life and the health sciences. apply knowledge of quantitative chemical methods to chemical calculations, including application of the mole concept to stoichiometry and the use of dimensional analysis. demonstrate the ability to perform basic chemical laboratory procedures using common laboratory equipment and to analyze the data collected. develop chemical formulas from chemical names and vise versa for elements, ions, acids, ionic and molecular compounds. formulate balanced chemical reaction equations and predict states of matter from solubility rules. develop a general knowledge of the make-up of the atom and how it relates to periodic trends in chemical properties and chemical bonding. differentiate between the characteristics of the three states of matter, the role of intermolecular forces in liquids and solids, and quantitative relationships of variables affecting behavior of gases. identify the properties of acids and bases (and their conjugates) with the ability to convert back and forth between acid concentration and ph. demonstrate a basic understanding of nuclear chemistry and its applications to medicine. interpret simple organic chemical formulas and structures in relationship to VSEPR theory.

OTHERWISE, YOU WILL BE DROPPED FROM THE CLASS TO MAKE ROOM FOR A STUDENT WHO HAS COMPLETED THE REQUIRED PREREQUISITES. IF YOU ARE DROPPED AND YOU ARE LATER ABLE TO PROVIDE DOCUMENTATION OF MEETING THE PREREQUISITE REQUIREMENT, YOU WILL BE RE-ADDED TO THE CLASS IF SPACE PERMITS. REQUIRED Materials: Textbook: The textbook I will be lecturing from is: Fundamentals of General, Organic, and Biological Chemistry, 8th th Edition by McMurry, Ballantine, Hoeger, and Peterson. (Prior 4 th 7 th editions with varying authors all starting with McMurry are acceptable substitutes. See correlation table at end of syllabus.) 8 th ed. 7 th ed. 6 th ed. 5 th ed. 4 th ed Custom ed. Mastering Chemistry Access Code for 8 th Edition (comes with new book or online at masteringchemistry.com) Laboratory Manual for Chem 305: by SCC Faculty (Fall 2016 Edition). Safety Goggles: indirectly vented such as sold in the SCC bookstore. Scantron: 4 forms, 50 questions per side (#882) Scientific Calculator: with log capabilities and scientific notation. I HIGHLY recommend the TI-30XA. I will be able to give you help with your calculator ONLY if you purchase this one. No programmable calculators. Blue or black pen, #2 pencil, red pen. 3 ring binder (~2.5-3 ) and divider tabs. Taboo Materials! Cell phones and computers are NOT to be turned on or in use at any time during lectures or exams. If you need a computer for lab work, they will be provided to you or you may use your own. Cell phone calculators may NOT be used for exams. Page 2 of 10

3 TIME REQUIREMENTS: The class meets for four hours of lecture and 3 hours of laboratory each week. An additional 9-11 hours a week will be required to read your textbook, answer homework questions, prepare for lab, complete lab write-ups, and study for exams. This totals hours a week, a minimum amount of time required for success in this course. History has shown that it is not feasible to succeed in chemistry 305 without putting in a large amount of time. If your outside commitments (family, work, other classes) will not allow you sufficient time for this course, please consider postponing this class until sufficient time is available. Lecture: M/W 9:45am 11:50am (LH203) (LEC 17836) Tu-Th 9:45am 11:50am (LH201) (LEC ) Laboratory: M 1:15pm 4:30pm (LH212) (LAB 17837) OR W 1:15pm 4:20pm (LH212) (LAB 17838) LECTURE: Tu 1:15pm 4:20pm (LH212) (LAB ) OR Th 1:00pm 4:20pm (LH212) (LAB ) Studies have shown that there is a very strong correlation between attendance and good grades. For instance, one such study indicates that students who miss at least one out of five lectures receive an average GPA less than 1.5! The point is that nearly every instructor--and I am no exception-- takes most exam questions directly out of the lecture material. Additionally, I will be explaining, as clearly and carefully as I know how, what you need to know about the subject. So try not to miss one single lecture all semester. (And please show up on time!!!) Students are responsible for all material presented in lecture, even if it is not covered in the textbook. STUDENTS WHO MISS MORE THAN 3 LECTURES MAY BE DROPPED UNLESS SPECIAL ARRANGEMENTS ARE MADE WITH THE INSTRUCTOR. LABORATORY: The laboratory experiences are an integral part of the class. They not only serve to reinforce lecture concepts, but also will be used to introduce new ideas and to provide you with the opportunity to be an experimental scientist. Work Checks: Within your lab manuals, you will notice work check points every couple of pages. WHEN YOU ARRIVE AT ONE OF THESE POINTS, YOU MUST COME UP TO THE INSTRUCTOR S DESK AND HAVE YOUR WORK INITIALED BEFORE PROCEEDING FURTHER. This is to give you real-time feedback on your work and to be sure that you are on the right track before going on. FAILURE TO OBTAIN INSTRUCTOR INITIALS IN THE WORK CHECK BOX AS YOU GO WILL RESULT IN A LOSS OF POINTS!! Please put your name on EVERY PAGE of your lab report. This will help me to get to know your names as you come up for your work checks. The laboratory portion of this course consists of laboratory experiments and workshops. Most of the labs/workshops can be found in the lab packet available for purchase at the college bookstore. Some of the labs/workshops are under construction and you will be given copies of these later in the semester. You can earn up to 10 pts for each lab or workshop. You must attend the entire workshop/lab to earn the maximum points. The lowest lab score will be dropped from your point total. Laboratory reports are due at the start of the next lab class unless stated otherwise during class. Page 3 of 10

4 Come prepared for lab!! Take a few minutes and read over your lab procedure / lab questions before coming to lab. If you have a basic understanding of what the lab is about before coming to lab it will help you and your lab partner work more efficiently in lab. Laboratory is a mandatory portion of the course. If you miss more than 2 laboratory sessions you will be unable to earn a passing grade. In order to earn an A or B grade in this course you can miss only one lab. Each lab is offered 4 times during the week. You have been provided with a schedule of when each lab is performed. In the event that you cannot make your own lab session, you may be able to make it up by coming to the other session. Note: Coming to another lab session other than the one you are registered for MUST BE APPROVED IN ADVANCE BY THE INSTRUCTOR. There are a limited number of lab spaces available for each day. Attending other sessions will be permitted based on space availability. Safety glasses/goggles must be worn at all times in the laboratory once the initial laboratory introduction lecture is over. You must have your goggles with you at the beginning of the third week of lab or you will not be allowed to begin lab work! Appropriate footwear for lab is closed toe shoes. No food or drink is allowed in the laboratory at any time. You are responsible for the equipment and condition of your locker. You will start out the semester with 10pts for good lab culture. If you break or lose equipment during the semester, forget your goggles, wear open toe shoes, collect data in pencil, etc., points will be subtracted from you lab culture total. HOMEWORK: Reading assignments should be completed PRIOR to attending the lecture on that material. Homework problems are assigned to help you!!! Students who "practice" chemistry by doing problems regularly in a thoughtful, logical manner are those who have the most success with the class. Some students prefer to work alone, others in study groups. At any rate, it is important that each student learns to tackle solving problems. Homework assignments are a crucial aspect of this course. Your homework is designed to reinforce lecture material. Just like learning to play the piano or becoming good at a sport, being proficient at chemistry and problem solving requires practice! Homework will primarily consist of assignments on masteringchemistry.com. Course Code for Mastering Chemistry is: NUSS2017FALLMW NUSS2017FALLTR. for Mon/Wed class for Tu/Th class Page 4 of 10

5 You will need to complete 85% of all assigned problems in order to receive full credit for homework points. These credits are cumulative for the entire semester. This means you can make up for an assignment where you did less than 85% by completing another with greater than 85% completeness. Your score will be based on a comparison to 85% of the possible credits. (It is not possible to get more than 100% credit for homework. Any score between % of the possible credits will receive 100% of the available homework points.) Ten (10) homework credits equal one course point. Homework Points Calculation Example 1: Completing at least 85% of the homework (on average) Assignment Possible Credits 85% of Possible Credits Your Credits Your HW points #1 30 (3.0pts) 25.5 (2.55pts) 22.5 (2.25pts) (75%) #2 50 (5.0pts) 42.5 (4.25pts) 47.5 (4.75pts) (100%) Total 80 (8.0pts) 68.0 (6.80pts) 70.0 (7.00pts) (87.5%) 6.80 out of 6.80 (100%) The most you can get is (6.80 is 85% of 8.00 pts) Homework Points Calculation Example 2: Completing less than 85% of the homework (on average) Assignment Possible Credits 85% of Possible Credits Your Credits Your HW points #1 30 (3.0pts) 25.5 (2.55pts) 12 (1.20pts) (40%) #2 50 (5.0 pts) 42.5 (4.25pts) 24 (2.40pts) (48%) Total 80 (8.0pts) 68.0 (6.80pts) 36 (3.60pts) (45%) 3.60 out of 6.80 (53%) Homework will be due at 11:59pm on the date shown in your Mastering Chemistry account. Any portion of the assignment completed prior to the deadline will receive full credit. Any portion done after the due date will be reduced in value at a rate of 25% per day. The time requirement stated in the title of each homework assignment (typically 4-5 hours) is the AVERAGE amount of time required to complete the assignment. About half of you will require significantly more time than that. Don t leave it all until the end. Try to do some problems every night. The problems are assigned in the same order we will be covering the material in class. GRADING PROCEDURE: Item Points Approx % of grade 1. Exams: 3 exams at 200 points. 600 ~44 The lowest exam score (including any one zero for a missed exam)* may be replaced with the percentage obtained on the final exam if that exceeds the lowest exam score, but not to exceed your highest other exam score. 2. Quizzes: minimum 7 lecture quizzes at 20 pts each. 120 ~9 (Lowest one dropped) 3. Nomenclature Quiz 60 ~4 4. Homework: 11 assignments (13-18 pts each)(~1400/10 * 0.85) 119 ~9 5. Laboratory Reports: See "Laboratory" section. 160 ~12 6. Final Exam: Comprehensive for the semester 300 ~22 7. Lab Culture 10 ~1 8. Total** ~ *If you must miss an exam day and, in the opinion of the instructor, there was a legitimate reason why the exam could not be taken on time and the student has come to lecture and done the homework assignments for that unit, the student will be assigned a grade equivalent to their percentage on the final exam. If more than one exam is missed, the student will be dropped from the class or given an incomplete, at the discretion of the instructor. **The total and distribution of points is tentative and may be adjusted at any time during the semester at the discretion of the instructor. Page 5 of 10

6 GRADING DISTRIBUTION: As a general guide, the following % of total points will be used to determine the final grade. These %s will not be raised; however, it is possible they might be lowered at the discretion of the instructor - but don't count on it!!! A (90.0% and above) B ( %) C ( %) D ( %) In addition to "absolute points," other factors will be considered for borderline cases including individual effort and thoughtful, prepared work in lecture and lab, safe lab practices, creativity, cooperation, and willingness to surmount obstacles. EXTRA CREDIT Extra credit falls into two categories: Unlimited and Limited Unlimited extra credit points are based on demonstrated mastery of specific chemistry topics. They may be accumulated from correctly answering extra credit questions posed at the end of tests and quizzes. There is typically limited partial credit given on extra credit questions. These points will not be kept track of separately during the semester, but will be added directly to your score on that test or quiz. Limited extra credit points are based on additional study effort. There are a variety of ways in which you can accumulate these extra credit points, but you are limited to a maximum of 14 extra credit points in this category for the semester (or an increase of 1% in your total grade). Some examples of ways in which to gain extra study points are to attend Beacon tutoring, develop a study group, attend tutoring at the LRC, or attend workshops or lectures that may be announced throughout the semester. Two times per week BEACON PROGRAM: By attending a Beacon study group, you may obtain up to 14 points of limited extra credit. To earn these points, you must (i) attend and participate in >85% of both Beacon sessions each week, (ii) keep a written record of the problems solved in each beacon session and (iii) turn in the record at the end of the semester. If you do not attend >85% of both sessions, then no credit will be given. You may qualify for the one time per week session. See below. One time per week BEACON PROGRAM: Similarly, if you attend one Beacon session each week and meet the above requirements, 7 points of limited extra credit will be awarded. Tutoring: Extra credit points can also be accumulated by attending weekly tutoring sessions at the LRC. This will require that you turn in a printout from the LRC logging the hours that you have attended. You will receive 1 limited extra credit point for every 2 hours of tutoring up to a maximum of 14 points. Study Group. If you cannot make it to Beacon because of a schedule conflict, you can start your own study group. A study group should consist of at least 3 people in order to get the benefit of the group dynamics. Each meeting of the study group, members should take turns coming up with materials for the group to use. Each member of the group should retain all dated workpapers from the study sessions to turn in at the end of the semester. This needs to be a semester-long commitment to get together to do work above and beyond that assigned in the course. Simply meeting to study for the exams will not qualify for extra credit!

7 CLASSROOM POLICIES: Cell Phones: Please turn off all cell phones or place them on vibrate during lecture and discussion. One accidental ring will be tolerated. Subsequent class disturbances will result in a loss of 5 points per occurrence. Tardiness: Please make every effort to be on time for class. If you must be late, please take your notebook, pen, etc out of your backpack before entering the classroom and take a seat in the rear of the room making every effort not to disturb those who arrived on time. Students are responsible for obtaining any missed material from another student at the end of class. If a quiz is given that day, it will usually be given at the start of the period and no additional time will be given to those who arrive late. On exam days, students arriving late will be held in the hall for the first 10 minutes and let in as a single group to minimize disruption to the rest of the class. Students will be given assigned seating for exams. Talking: Talking is disruptive to other students in the class. If you are asked to stop talking more than once during a class period, you may be asked to remove yourself from the classroom for the remainder of the period. You will still be held responsible for the information presented during the remainder of the class period, or possibly a 2-day suspension. Accommodations: Some students may require special accommodations. If you feel you need an accommodation, please come and see me outside of class time to discuss this in person. Cheating: For the first occurrence of cheating, a student will receive a zero for that assignment and they will be referred to the college for disciplinary action. To be clear, you will receive a grade of zero for: Allowing (even passively) another student to copy your work. Copying another student s work and submitting it as your own. Copying work from previous semester s students. Using materials not allowed for exams or quizzes. Looking at another student s exam/quiz for answers during the exam/quiz. Letting another student see your work during an exam/quiz. Using a lab manual or lab book from a previous student in this class. Plagiarizing (or directly copying) work from the solutions manual. Note: The preceding set of policies and procedures for Chemistry 305 were developed based on the best information available at the time of production of this syllabus. The instructor reserves the right to make changes as necessary as the course proceeds. Page 7 of 10
