I am available 30 minutes before the class starts to hear your concerns and just to discuss course topics. COURSE DESCRIPTION: CHEM 1412 is the continuation of chem course which is intended to show students the importance of chemistry in their major area of study as well as its applications to their daily lives. It provides the necessary background for specialist studies. The laboratory includes appropriate experiments to strengthen the knowledge and application of the course topics. PREREQUISITE: CHEM 1411 OR its equivalent Course Goals: Have science and engineering majors able to translate the theoretical concepts of Chemistry into concrete terms. Student Learning Outcomes The student will be able to: 1. Calculate the molar mass of an unknown compound using colligative properties. 2. Determine the rates of reactions. 3. Predict the effects on equilibria based on le Chatelier s principle. 4. Write equilibrium constant expression 5.

Tuesday and Thursday in Rm- 519 LABORATORY POLICY Laboratory rules and safety instructions will be reviewed and observed. Eye protection is very important. During wet labs, eye glasses or goggles must be worn at all times during the laboratory period. Any student not wearing safety glasses at any time after the experiment has begun may be given a zero for that experiment. Laboratory reports are due one week after the experiment. Lab report will be submitted by each student individually. Identical and late lab reports are not acceptable. Students must come prepared to lab by reading and completing pre-lab activity for the given lab. THERE WILL BE NO MAKE UP LAB: Students are expected to attend every lab. Students are responsible to contact the instructor if any lab is missed, and make-up assignment should be submitted within one week of the missed lab. Student Conduct Be seated on time.

3 Respect yourself and others Classroom Discussion should be relevant to the topic Re respectful to the instructor during the lecture period ( avoid interruption by talking) Cell phone and other electronic device should be turned-off before you enter the class. You may have a seating chart (if needed) by the instructor. Camera Phone and recording devices are not allowed to use in the class (refer to HCC- ADA policies for reasonable accommodations) Student is asked to behave as a responsible adult. You may ask to leave that day s class for inappropriate behave, and will receive a grade of F for the course for repeating VIOLATIONS. DISABILITY SUPPORT SERVICES (DSS) Any student with a documented disability (e.g., physical, learning, psychiatric, vision, hearing, etc.) who needs to arrange for reasonable accommodation must contact the disability Services Faculty is authorized to provide only the accommodation requested by the Disability Support Services Office. Academic Dishonesty: Students must conduct themselves with honor and integrity to fulfill the course requirements. Disciplinary action may be initiated by the college system against a student accused of Scholastic dishonesty. Penalties may include a grade of F on the particular assignment, failure in the course, academic probation, or even dismissal from the college. Scholastic dishonesty includes, but is not limited to, cheating on a test, plagiarism, and collusion. A Cheating on a test includes: Copying from another student s test Un authorized materials are used during the test Collaboration with another student during the test Buying, selling, stealing, transporting or soliciting in whole or part of the contents of an un administered test; or bribing another person to obtain a test that is to be administered Plagiarism means the appropriation of another s work and the unacknowledged incorporation of that work in one s own written work for credit. Collusion means the unauthorized collaboration with another person in preparing written work offered for credit. In this case, the penalty will be F for this course. This is the standard policy for the Physical Science department of the Northwest Campus. ATTENDANCE AND WITHDRAWAL POLICIES: The HCC attendance policy states that students are expected to attend classes regularly. Class Attendance will be checked daily. Three tar dies / early exits are counted as one absence. Students are responsible to make up their missing works. It is their responsibility to contact the instructor to make-up their missing assignments. Students can withdraw from the class and receive a grade of W up until the last day to drop from a class for this semester. The instructor cannot give a W when the student is failing at the end of the semester. Students remaining and participating in class after the official withdrawal date will receive a grade. Students will receive a grade of I only if they have completed all course requirements with the exception of the final examination. An Incomplete (I) will automatically be converted to an F after one semester unless the required work is completed. Instructor can drop a student for excessive absences. Policy Regarding Multiple Repeat of a Course: Students who repeat a course three or more times may want to withdraw the course because you are not making the passing grades. Contact your instructor or counselor as early as possible. You

4 may need to change your study habits, reading and writing homework, test taking strategy, attendance, class participation, tutoring and other opportunities that might be available. Instructor Requirements As your Instructor, it is my responsibility to: Provide the grading scale and detailed grading formula explaining how student grades are to be derived Facilitate an effective learning environment through class activities, discussions, and lectures Description of any special projects or assignments Inform students of policies such as attendance, withdrawal, tardiness and make up. Provide the course outline and class calendar which will include a description of any special projects or assignments Arrange to meet with individual students before and after class as required To be successful in this class, it is the student s responsibility to: Attend class and participate in class discussions and activities Read and comprehend the textbook Complete the required assignments and exams: Ask for help when there is a question or problem Keep copies of all paperwork, including this syllabus, handouts and all Assignments.

Examinations will be based on lectures, practice exercises, and homework exercises. Points earned in quizzes and/or homework will be included in calculating the grade for a non-cumulative regular exam. GRADING The course grade is based on the following: Three regular exams 60% Laboratory 20% Final exam 20% The course grade is calculated as follows: Course Grade = (best of 3 regular exams) + (laboratory Grade) + (Final Exam) / 5 Letter Grades: % = A 80-89% = B

6 70-79% = C 60-69% = D 00-59% = F Online Home work: Owl V2 homework assignments (Chapter mastery and chapter tests), which will be counted for 5% extra credit. 5% extra credit will be counted for End of Chapter problems.

If anything happen, you will be notified in advance. Lab reports are due by the next class after you finish your lab. You should prepare your lab report on your own (individually). The website available on Eagle Online at will be used as an instructional aid. EGLS3 -- Evaluation for Greater Learning Student Survey System at Houston Community College, professors believe that thoughtful student feedback is necessary to improve teaching and learning. During a designated time, you will be asked to answer a short online survey of research-based questions related to instruction. The anonymous results of the survey will be made available to your professors and division chairs for continual improvement of instruction. Look for the survey as part of the Houston Community College Student System online near the end of the term.
