Literature Resources:

class text –Catalyst: The prentice hall custom laboratory program for chemistry , Pearson Prentice Hall
web literature - some useful resources are

• American Chemical Society: http://www.chemistry.org/portal/a/c/s/1/home.html The world's largest scientific organization, with information on virtually every issue of interest to chemistry professionals...
• Chemistry Comes Alive : http://jchemed.chem.wisc.edu/JCESoft/CCA/CCA6/MAIN/HOME.HTM A good introduction to general chemistry and a detailed description of each experiment.
• NIST Chemistry WebBook: http://webbook.nist.gov An excellent on-line reference for lots of physical and chemical data

Objectives: Consistent with the goals of the UNCP General Education Program (see p. 23 of the UNCP catalog), the activities associated with this course are designed to provide students an understanding of the fundamental principles of chemistry and to foster the ability to quantitatively analyze data, to write and speak clearly, and to think critically and creatively.

Lab safety: Students must follow all written and verbal instructions regarding safe lab procedures. A written copy of lab safety policies will be provided. Failure to comply with these rules may result in dismissal from the lab. Eye protection must be worn at all times in the lab.

Description: This lab will try to reinforce the concepts presented during the lecture about: composition, structure, and properties of matter, including stoichiometry, atomic and molecular structure and theory, and chemical periodicity.

Format: Each lab will start with a lecture that will describe the experiment. After the lecture the students will start the experiments under the supervision of the instructor. Because of the importance of the safety in chemistry, students should bring scientific calculators , lab coat and appropriate safety eyewear. All the experiments will be described in a quad ruler bound notebook (available from the instructor).

Any student with a documented learning, physical, chronic health, psychological, visual or hearing disability needing academic adjustments is requested to speak directly to Disability Support Services and the instructor, as early in the semester (preferably within the first week) as possible.  All discussions will remain confidential.  Please contact Disability Support Services,  DF Lowry Building, Room 103 or call 910-521-6695.

Course Requirements: Graded assignments for this course will include the lab reports, one midterm test and a comprehensive final exam. Pertinent questions and problems will frequently be suggested for work outside of class, though submission of these assignments is not required.

Evaluation/Grading: Course grades will be computed on a 4-point scale based on evaluation of a laboratory notebook (10%), 9 written lab reports (60%), a midterm test (15%) and a final examination (15%). All lab reports are due the next week following the experiment. For each day of delay you lose 10% of the grade. Now lab report will be do after 10 days.

Letter grades for the course will be assigned according to the scale described in the University catalog (see the relevant section of Academic Procedures and Policies").

Attendance:   Attendance at all scheduled lab sessions is required. There will be no make up labs. If absence is unavoidable, excuses must be written and submitted one week prior to or following the absence. Additional documentation may be required. Unavoidable absences are considered for personal or immediate family illness, death in the immediate family, or business commitments that are verified by your employer in writing. Missed labs that do not meet the above criteria will result in a grade of “0”. No student will receive credit for the lab if he or she misses in excess of two lab periods. For religious holiday policy please refer to the following website for details: http://www.uncp.edu/chem_phy/religiousholidaypolicy.pdf.

Honor Code:  Students are expected to follow the UNCP Honor Code (see pp. 49-51 of the UNCP catalog); settled cases involving first-offense violation of the Honor Code will result in a minimum penalty of course failure.

Good Communication: It is the best way to avoid problems and misunderstandings. Please discuss any questions or concerns you may have about this course or general policies with me.
