Course Description CHEM 120 is the second course in a two-semester sequence of General Chemistry. These two courses cover the fundamental principles and applications of chemistry designed for science and chemical engineering majors. In order to succeed in this course, it is necessary to have a firm grasp of those topics presented in CHEM 119. The aforementioned topics will be referred to and utilized throughout the semester; however, it will not be reviewed in depth. In this 4-credit course, students will be introduced to chemical kinetics and equilibria; the behavior of solutions; the chemistry of acids, bases, and buffer solutions; thermodynamics; electrochemistry; and nuclear chemistry. Since this is an integrated lecture/laboratory course, both components are required in order to pass the course.

Course Prerequisites CHEM 119 or CHEM 107 and CHEM 117

Course Syllabus Special Course Designation CHEM 120 meets the state requirements for Core Curriculum in Life and Physical Science. Courses in this category focus on describing, explaining, and predicting natural phenomena using the scientific method. Courses involve the understanding of interactions among natural phenomena and the implications of scientific principles on the physical world and on human experiences. Core objectives for the Life and Physical Sciences Foundational Component Area: 1. Critical Thinking: Includes creative thinking, innovation, inquiry, and analysis using evaluation and synthesis of information. Students will meet this core objective through free response questions on exams, problems presented during lecture, assignments completed in Canvas, and the analysis and evaluation of data from laboratory experiments. 2. Communication: Includes effective development, interpretation, and expression of ideas through written, oral, and visual communication. Students will meet this core objective through in-class pair discussions, the creation of succinct tables and graphs using experimental data, well-written result and conclusion summaries of laboratory experiments, and a short experimental demonstration and explanation of a chemistry concept/topic of the student’s choice. 3. Empirical and Quantitative Skills: Includes the manipulation and analysis of numerical data or observable facts resulting in informed conclusions. Students will meet this core objective by applying theoretical and quantitative concepts presented in lecture to “real-world” problems as well as the interpretation of experimental data from laboratory experiments. 4. Teamwork: Includes the ability to consider different points of view and to work effectively with others to support a shared purpose or goal. Students will meet this core objective by working in pairs or small groups to solve problems in lecture as well as setup and execute laboratory experiments.

Course Learning Outcomes By the end of this course, students will be able to: •

Understand colligative properties and their use in determining the characteristic of solutions.

•

Write equilibrium constant relationships, determine whether equilibrium has been established and calculate equilibrium concentrations including applications of equilibrium concepts to precipitation and solubility.

•

Use LeChatelier’s Principle to predict the effects of concentration, pressure and temperature changes on equilibrium mixtures.

•

Describe how reaction mechanisms are determined; carry out chemical kinetics calculations, state how rate and equilibrium properties are related.

•

Understand Bronsted-Lowry, Arrhenius and Lewis acid-base theory including pH calculations and buffer action.

Course Syllabus Optional Course Information Items Questions: If you have any questions regarding the lecture, please contact Dr. Bethel via email. For questions regarding the laboratory or specific experiments, e-mail your TA. General questions regarding other non-technical issues can be sent to [email protected]. Communication and Conduct: All electronic communication with your Lecture and Lab Instructors, TA, IA, and the FYP office must be conducted from a tamu.edu email account. Emails sent to university email addresses are a permanent document of communication. Therefore, be sure that your emails are polite, professional, and wellprepared before you send them. All emails should include the student’s first and last name, UIN, and the course and section number. Students are responsible for checking their tamu.edu email on a regular basis to receive messages regarding the course. Please allow up to 48 hours for a response to emails. Responses will normally occur between 8 am and 4 pm, Monday through Friday. Inappropriate language and/or disruptive behavior can result in loss of credit and/or reported to the Student Conduct Office. Canvas: All lecture grades will be posted on the Canvas pages (http://canvas.tamu.edu) related to the course. Various announcements, lecture material, supplemental information, practice exams, exam keys, and/or handouts will be posted on the Canvas page. All Hayden-McNeil Online assignments and prelab quizzes can be accessed through the Canvas page. Disclaimer: Any communications or handouts from your Lecture Instructor, Lab IA, the FYP office, or Lab Instructor take precedence over the contents of this syllabus. Homework: Homework problems will be assigned after each lecture. They will be worth a total of 100 points for the semester. Homework MUST be turned in on time. All assignments will be due the evening after the lecture in which the information was presented, just before midnight. Because all homework is online, the cutoff is very strict. Do not wait until the last minute to do your homework! The purpose of homework is to prepare you for exams, and to ensure that you understand all topics covered in lecture. Homework will be assigned and graded using the ALEKS Learning System. ALEKS is an artificially intelligent assessment and learning system designed to determine which topics a student has already mastered and which new topics they are ready to learn. The topics within each assignment may be worked on repeatedly until a topic is learned (or mastered) until the posted due date. Completing each topic will add to your overall ALEKS pie. You will also have the opportunity to complete missing topics around each exam. Your grade will be taken from the number of Page 7 of 15

Course Syllabus topics learned (or mastered) by that topic’s due date. Each of these 23 assignments is worth 4/100 ALEKS points. The overall mastery of topics (percent completion of the ALEKS pie) will be the last ALEKS assignment and is counted as a double assignment (8/100 ALEKS points). Class Participation: The course will be conducted using a flipped-classroom design. Links to the lecture topic videos for each lecture are posted in Canvas. It is expected that these lecture topic videos are viewed PRIOR to attending class. Included in each lecture topic video will be at least one question that must be answered on Canvas. These questions will be equivalent to questions that will be seen on the exam. The purpose of these questions is to prepare you for the level of difficulty on exams. During the lecture time, I will present additional subject information, as well as mathematical and concept-based problems related to the day’s lecture topic videos. Students will be given time to work through the questions and respond using the iClicker Student polling app. After responses are collected, I will solve each problem step-by-step. The window for answering the Canvas questions will be available from 12:00 AM of Monday or Wednesday until 11:59 PM on their due date of Tuesday or Thursday. Participation points will be awarded based on accuracy of submitted answers. Only 75% accuracy on both iClicker Student polling questions and Canvas questions is required to gain full credit toward each portion of the participation points. Participation points are assigned as shown in the table below.

iClicker Student Percentage 75% - 100% 70% - 74% 65% - 69% 60% - 64% 55% - 59% 50% - 54% 40% - 49% 30% - 39% 20% - 29% 10% – 19% 0% – 9%

Course Acknowledgement Quiz: The CAQ indicates that you have read and understand the syllabus, set-up the REEF polling app on your smartphone, and registered and begun working on homework in ALEKS will be posted on Canvas. It is due by Wednesday, January 26th by 11:59 pm. You will be allowed unlimited retakes until you are able to answer all questions correctly for ten (10) points. Page 8 of 15

Course Syllabus

Exams: There will be four (4) exams given in class on the days indicated on the Lecture Schedule (page 5). Each exam will cover the material listed in the objectives as noted in the course syllabus. You are responsible for these objectives even if the material is not expressly covered during the lecture. All exams are comprehensive and may include previously covered material. The format of the exams may be free response, multiple choice, or a combination of the two. Please note that while the lecture period is 75 minutes, the exam time will be 50 minutes. Lecture Exam Administration: •

•

Assigned seating will be arranged and posted in Canvas prior to each exam. Each exam will have a different seating assignment. If you require special seating, please make your request to the instructor AS SOON AS POSSIBLE. The request only needs to be made once for the entire semester. Arrive to the exam on time. Late arrivals will not be given any time extensions.

•

Bring at least two sharpened #2 pencils, a photo ID (TAMU ID or driver’s license), and an appropriate calculator (see required materials for specifications). All other items must be stored away completely in a book bag under your assigned seat. Calculators may not be shared during exams.

•

Follow all directions given regarding the exam. These directions will be written on the cover page of the exam and will be announced before the exam beings. Additional announcements regarding time remaining and error corrections may be made at any time during the exam.

•

All answers must be written in the indicated space for each question. Failure to properly fill in identifying information (i.e., name, UIN, section number, etc.) will result in a loss of points. Keep your exam answers covered as much as possible. Talking or looking around the room may result in a withheld grade for the exam. Work efficiently through the exam. All exams must be turned in on time. Late exams will not be graded. If you finish your exam early, you may turn it in and quietly exit the room. Any student failing to follow instructions may lose points or receive a zero for that exam. Exam grades will be posted as soon as possible on Canvas. If you wish to review your exam, it will be viewable using Gradescope

• • • •

Comprehensive Final Exam: The final exam will cover all the material presented throughout CHEM 120 as well as all associated material from CHEM 119. The exam period is 2 hours; therefore, the final exam will be approximately twice the length of a normal in-class exam. The date and time for the final exam can be found in the lecture schedule above.
