1 General Chemistry I, CHEM 1411 Blinn College Bryan Campus Course Syllabus Fall 2011 Instructor: Mr. Wayne Harshbarger Office: S117 Office Hours: MW 7:00 AM 7:45 AM; other times by appointment Phone: Course Description: The course consists of the study of the fundamental laws, theories and concepts of chemistry including quantitative relationships involving mass and energy, the structure and properties of matter, the chemical and physical changes that matter undergoes and the study of solution chemistry. Prerequisites: MATH 1314 or 1414 with a grade of C or higher or an SAT math score of 550 or higher or an ACT math score of 22 or higher. Core Curriculum Course: This is a Core Course in the 42-hour Core of Blinn College. As such, students will develop proficiency in appropriate Intellectual Competencies, Exemplary Educational Objectives and Perspectives. The URL of the Blinn College core curriculum website is: Course Objectives and Student Learning Outcomes: Students who complete this course should gain an understanding of the topics listed in the course description and should be able to analyze, evaluate and solve problems related to those topics. Students should also be able to safely perform basic skills needed to investigate the course topics in laboratory. At the completion of the course, the student will be able to: 1. Name, identify, and classify inorganic chemicals. 2. Convert between mass, number of moles, and number of particles of a substance. 3. Balance chemical equations and use the balanced equation to determine limiting reagent, theoretical yield and percent yield. 4. Use the atomic model to define the electron configurations of an atom and its properties given the position in the periodic table. 5. Given a covalent compound, draw its Lewis structure then predict the type of hybrid orbitals, the molecular shape, the polarity of the compound, and whether resonance occurs. 6. Identify substances as acids, bases, or salts and use stoichiometry to determine molarity in acid-base titrations. 7. Use the concepts of an ideal gas to determine changes in conditions, density, molecular weight, and partial pressures. 8. Compare and contrast the properties of gases, liquids and solids and interpret a diagram of the phases of a pure substance to define phase changes and key points (critical point and triple point). 9. Identify various intermolecular forces of attraction and correlate these with physical properties of various substances. 10. Calculate an approximate heat of reaction from the bond energies of the reactants and products and correlate bond energy with bond order and bond length for cases involving the same two atoms. 11. Correlate the signs of enthalpy and entropy with the heat and order changes in a reaction. 12. Calculate heat involved in a reaction given heats of formation and use the heat in stoichiometry calculations. Textbooks and Other Materials: Text: "Chemistry", McMurry and Fay, 6th Edition, Homework: Online Web-Based Learning (OWL) access code Appropriate eye protection: 1. Safety goggles (required if contact lenses are worn) 2. OSHA approved safety glasses with side shields Laboratory Manual: General Chemistry 1411 Laboratory Manual, Clement, Lab notebook: 8 1/2" x 11" carbon copy, perforated pages.

2 Optional Materials: Laboratory apron, or a nonflammable lab coat. An apron or lab coat will be required in laboratory if your shorts or skirt do not cover your knees while standing. Course Content and Schedule: See the attached tentative schedule at the end of this document. Civility Statement: Members of the Blinn College community, which includes faculty, staff and students, are expected to act honestly and responsibly in all aspects of campus life. Blinn College holds all members accountable for their actions and words. Therefore, all members should commit themselves to behave in a manner that recognizes personal respect and demonstrates concern for the personal dignity, rights, and freedoms of every member of the College community, including respect for College property and the physical and intellectual property of others. Civility Notification Statement: If a student is asked to leave the classroom because of uncivil behavior, the student may not return to that class until he or she arranges a conference with the instructor. It is the student s responsibility to arrange for this conference. Course Requirements and Policies: Absences A severe personal problem such as illness or a death in the family may, with adequate documentation, warrant special academic consideration during the ongoing term for making-up certain work or turning in certain materials late. However, the difficult situation is not in itself an excuse for failure to meet the course requirements. If such a situation arises it is the student's responsibility to inform the instructor immediately of the situation and the surrounding circumstances. Supportive documentation must be provided regardless of the circumstances. Make-up work may or may not be given for unexcused absences. I do not provide copies of missed notes to students; therefore, make arrangements with another student to get the notes. Reading is a requirement. Lectures and readings are designed to help you develop an understanding of the material being emphasized. Sometimes I will ask you to read material before you come to class and other times after a lecture is delivered. Please pay attention to announcements in class as to where you should be with the readings. Homework is a requirement. There will be 4 assignments due during the semester worth 25 points each set (100 pts. maximum). Homework will be graded based on the following criteria: Homework is turned in on time The assignment is complete The answers are correct Homework collection and grading will be handled by the Mastering General Chemistry system. A code must be purchased in order to access this system. Further instructions are given at: The deadline for each assignment is the date/time of each Lecture Exam. Past due assignments are accessible until the day of the final exam. Quizzes are a requirement. There will be at least 5 pop quizzes during the lecture portion of the course. These quizzes will be given during the first 5 minutes of class and be worth 10 points each. The 5 highest scores will count for a maximum of 50 points towards your final grade. Exams are a requirement. There will be 4 Lecture Exams worth 100 points each given on the days indicated in the attached schedule. These exams may have a combination of multiple-choice questions that will be machine-graded and non-multiple choice questions that will be hand-graded. The Final Exam is comprehensive, all multiple-choice and worth 200 points. Laboratory Experiments are a requirement. The laboratory portion of this course counts for 25% of the total course grade. For each worksheet/experiment you will receive a total score between 0 and 13. The Lab Report must reflect information obtained by you while in the laboratory and recorded in your lab notebook. A Data Sheet from your lab notebook must be turned in before you leave; alternatively, a Lab Attendance Sheet must be signed. Lab Reports will not be accepted unless one of these has been completed for the experiment. Lab Reports must be turned in individually (i.e. each student must turn in an assignment). The Prelab Questions should be done prior to starting

3 the experiment. Prelab Questions/Report Forms/Postlab Questions are due at the end of the following lab report work day. Neatness and completeness of your data sheets, pre-labs, and reports may be considered when points are assigned. Points can be deducted for materials not submitted on the date due. There will be 12 experiments performed during the semester, of which 10 be counted toward the final course grade (130 pts. maximum) Laboratory Quizzes are a requirement. In addition, 4 Lab Quizzes based on laboratory material will be given during the lab period on the days indicated in the attached schedule. These laboratory quizzes are worth 30 points each. Students are responsible for purchasing and correctly wearing appropriate eye protection during the lab period. Students must wear approved eye protection and closed toed shoes any time chemicals or equipment are being moved by anyone in the laboratory. Failure to wear eye protection or appropriate footwear will result in expulsion from the laboratory for the experiment involved (the student will receive no points for that experiment).

Blinn College Policies: Attendance The College District believes that class attendance is essential for student success; therefore, students are required to promptly and regularly attend all their classes. Each class meeting builds the foundation for subsequent class meetings. Without full participation and regular class attendance, students shall find themselves at a severe disadvantage for achieving success in college. Class participation shall constitute at least ten percent of the final course grade. It is the responsibility of each faculty member, in consultation with the division chair, to determine how participation is achieved in his or her class. Faculty will require students to regularly attend class and will keep a record of attendance from the first day of class and/or the first day the student s name appears on the roster through final examinations. If a student has one week s worth of absences during the semester, he/she will be sent an by the College, via their Blinn account requiring the student to contact his/her instructor and schedule a conference immediately to discuss his/her attendance issues. Should the student subsequently accumulate two weeks worth of unexcused absences, he/she will be administratively withdrawn from class. There are four forms of excused absence officially designated by Blinn College: (1) Observance of religious holy days: The student should notify his/her instructor(s) not later than the 15 th day of the semester concerning the specific date(s) that the student will be absent for any religious holy day(s); (2) Representing Blinn College at an official institutional function; (3) official involvement in a high school activity for dual credit students; and (4) military service. Other excuses will be considered and may be considered excusable at the instructor s discretion, with documentation. Missing lecture or lab or both will count as one absence.

4 Dropping If a student chooses to drop the course, it is that student s responsibility to complete a drop order at the Office of Enrollment Services. Failure to do so could result in a grade of F in the course. The last day to withdraw with a Q is Friday, November 18 th. Eating and drinking are not allowed in classrooms or laboratories. Dishonesty Statement Blinn College does not tolerate cheating, plagiarism or other acts of dishonesty. Definitions of these acts and procedures for dealing with them are described in Scholastic Dishonesty in the Blinn College Student Handbook, copies of which are available at the information desk in the administration building. ADA Statement Students with physical or learning disabilities must present documentation from the Office of Disability Services to receive accommodation on exams and assignments. Accommodation is not retroactive. The above requirements and policies are discussed more fully in the Blinn College Student Handbook which, by reference, is incorporated into this information. Please obtain and read.
