On the average students need to study at least two hours for each hour spent in class. It is important to study regularly, preferably daily. 1
Homework Exercise: Your homework in this course will come from two different sources: (1) graded online assignments facilitated through a program called Mastering Chemistry and (2) Study exercises from your text which will be assigned on a regular basis that you can practice a certain principle. Each student is expected to complete all of the assignment on his/her own. Homework from the text will neither be collected nor graded. Mastering Chemistry- www.masteringchemistry.com/site Mastering Chemistry is a web based tutorial/homework program. A portion of your overall grade will be based upon the use of this software. Therefore, access code is required! Your access code is good for two years and follows you from course to course. You can purchase access code separately online from the publisher. If you are registered in Chemistry1C Section 02 then your course ID is REZAIECHEM1C02FALL10 Grading: Grading will be based upon two midterm exams, a comprehensive final exam, and laboratory work. When computing course grades, each student’s overall percentage will be determined from the following: 2 midterm exams (15% each) Comprehensive Final Online assignments 2 Laboratory quizzes (7.5% each) Laboratory Report Qualitative Analysis: Unknown Identification Subjective evaluation 30% 20% 10 % 15% 15% 5% 35% Laboratory Work 5% Subjective Evaluation 60% Lecture

SUBJECTIVE EVALUATION (5% of your grade) A subjective evaluation will be assessed at the end of the quarter to reward you for your good attendance and active/thoughtful participation, your preparedness for the laboratory sessions, your ability to follow both written and verbal instructions, your adherence to the safety rules, your cleanliness practices, and your overall respect for the laboratory through the proper care and use of all laboratory apparatus and instruments. Attendance and Dropping the course: It is required that you attend all lectures, labs, and to be on time for all scheduled meetings for this class. You are responsible for all the material covered in this course and if you must be absent, it is in your best interest to contact the instructor and check with classmate regarding material missed. Since this is an experimental course, your presence in the laboratory is essential for understanding of the materials covered. You may be dropped if 2 or more unexcused lab absences are counted. Allowances may be made for emergencies and other complications in life. Make-up Exams: Make-up exams will not be given. All exams are required and will count toward your grade. If you miss a midterm lecture exam you will receive a zero for the 10% of your final grade. The final exam is mandatory and cannot be missed. Failure to take the final exam will result in a failing grade. Incomplete grades are only given for verified illness or legitimate emergencies. If an incomplete is given, all exams and lab work prior to the incomplete are still counted in your grade; only material that has not yet been completed can be made-up in the future. You must be passing the course to receive an incomplete grade. Academic dishonesty:
3
Any form of academic dishonesty will be ground for dismissal from the course. It is your responsibility to understand what constitutes academic dishonesty in accordance with the Foothill College Academic Honor Code (www.foothill.edu/services/honor). Academic dishonesty includes: • Plagiarism (copying or allowing someone to copy) lab exercises or reports. • During an exam, communicating or transferring information to another student, • Receiving information from someone else, looking at another person’s exam, and/or • Using unauthorized materials such as text books, notes, etc. • Having another person complete and submit work in your name. • Lying to an instructor to improve your grade. • Altering a graded work after it has been returned and then submitting the work for regrading. Consequences of academic dishonesty may include: • A report of the violation to the Dean of Student Affairs and Activities; this office keeps a record of students who have engaged in academic dishonesty. Repeated violations may result in administrative action including probation, suspension or expulsion from the college. • You may receive an F grade on the work involved; this may also result in an “F” in the course. • Verified cheating on the online homework will result in a score of 0% being given for the homework grade. For incidences of lab exercise or report plagiarism, all parties involved will receive a reduced grade or grade of zero for the exercise or report Important dates: • • • • • First week: All adds will be processed. No one will be added after the first week. Second week: You can get a refund for your fees if you drop by the end of the second week. Fourth week: you can drop this course without a grade by the end of the 4th week. If you stop attending during this period I will drop you. Fifth to eighth weeks: you can drop and receive a “W” grade. Ninth week and beyond: If you attend, you will Not be given a W.
Class Rules and Regulations • • • • • • Arrive on time. Students who are late for lab lecture (more than 10 minutes) will not be allowed to do the experiment. Be polite to your instructor and fellow students Remain quiet during lecture. Taking to fellow students during lecture is disruptive to other students.

LABORATORY: Chemistry 1C/Rezaie
Since chemistry 1C is an experimental course, the presence of the student in the laboratory is essential for the understanding of the materials covered. A student may be dropped if 2 or more unexcused lab absences are counted. Missed labs cannot be made up unless you have my approval to make up the missed lab by attending an alternate lab meeting. You may miss one lab without penalty. I may allow for emergencies and other complications in life. Required Materials For Lab: 1. Laboratory packet of experiments and exercise for chemistry 1C. Available online at: http://www.foothill.edu/psme/daley/labpackets/1C packet.html 2. Scientific calculator: TI-83, 83-plus,-84 or 86 3. A copy of graphical Analysis software by vernier: supplied by the department for students to copy and return; you do not need to purchase a copy. Also, Graphical Analysis is available on the computers in the PSME Center for students to use. 4. Safety Goggles or Visorgogs: must be purchased from Foothill bookstore. Safety Rules: 1. Make sure you read and understand all of the safety rules. 2. Safety goggles must be worn at all times while working in the chemistry laboratory. NO EXCEPTIONS will be made to this rule. Any student who does not cooperate with this policy will be asked to leave the lab and will receive zero credit for the experiment. Students with prescription glasses will be required to wear safety goggles over their prescription glasses. Contact lenses should NOT be worn in the laboratory. Lab Procedure/Policies: 7
1.
2. 3. 4.
All students are expected to arrive to lab on time and to come to lab prepared to carry out the experiment scheduled for that session. This means that you have studied the experiment for the day, have a basic understanding of its purpose, procedure, and the chemistry involved. Before coming to lab you should do the assigned pre laboratory reading, read the background discussion and procedure and complete the pre laboratory exercises for the experiment. We ask that all students do a conscientious and thorough job cleaning up after themselves, whether it is in their own work area in lab, or shared areas such as the chemical supply table and balance room. When you work with a partner or group of students, you will share the data that is collected. However, you must do your own calculations and lab reports. As a concern for the environment, proper chemical disposal is essential. Students who do not comply with directed procedures may be dropped from the course for repeated offenses. Check with your instructor if you have any questions.
Laboratory Lecture: The beginning of each laboratory session is designated as laboratory lecture period. I will use this period to explain important details of the procedure, calculations, safety hazard and proper chemical disposal. If you are late more than 15 minutes late for lab lecture, you will not be allowed to perform the experiment for that day. Attendance: A student may be dropped when the total unexcused absences for this class exceeds three. These absences include those in which you arrive late for lab lecture and thus not allowed to do the experiment. I will allow for emergencies and other complications in life. Grading: Grading will be based upon: • • • Lab reports/assignments Two lab exams: Qualitative Analysis (unknown Identification) (15% of course grade) (15% of course grade) (5%of course grade)
Lab Tests Lab tests will be based on the laboratory experiments and exercise; and will cover the chemistry, calculations and conclusions of the experiments. Critical thinking is required.
Lab-reports are due one week after the completion of a lab experiment. There will be 10% penalty for late lab reports that are one lab period late. There will be 50% penalty for late reports that are two lab period late. No lab report will be accepted that is more than two lab period late. The lowest lab report will be dropped. 8
Lab Reports Format All your experimental lab reports must follow the following format:
1. TITLE: One line description of the title of the experiment 2. PURPOSE: Brief description of the goal or final outcome of the experiment. 3. INTRODUCTION: This part should consist of a paragraph describing the background
theory, concepts and principles upon which the experiment is based. It may also include statements about importance, relevance and perhaps particular applications of the experiment as well as a discussion of potential sources of errors. 4. EXPERIMENTAL METHOD: In this part you must list all equipment and reagents (with correct name and concentration) that are used in the experiment. You must also provide an experimental procedure outlining all major steps that must be followed to achieve the experiment’s goal. 5. CONCLUSION: This must consist of a brief discussion about the results obtained, whether they are consistent with your expectations and comments on any interesting or unusual observations. 6. ATTACHMENTS: All your experimental data, graphs and answered questions from your lab manual must be attached to this report.
Important Notes: 1. Items 1-5 must be typed. 2. Items 1-4 must be completed prior to the start of each lab. I will initial it before you are allowed to perform the experiment. Detailed guidelines for laboratory report preparation will be given in class. UNKNOWN IDENTIFICATION (5% of course grade): This is based upon the correct identification of the cations in your unknown during the qualitative analysis portion of the lab. You will lose points if you miss a metal cation that is present in your unknown. You will also lose points for false positives. As part of your unknown identification grade, you will be required to submit a flow diagram that accurately summarizes the steps that were required for identification.
CHECK LIST FOR COMPLETED LABORATORY ASSIGNMENTS/REPORTS: • Write your name on the first page. All loose papers must be stapled together! (No paper clips, no bent corners, etc.) Loose papers will not be accepted and if you do turn them in, points will be deducted! The lab report or assignment should be neat. Use pencil or pen. Mistakes during data collection should be crossed out with a single line (not erased!). All writing must be legible. On graphs, circle the points so they can be seen. INCLUDE UNITS on all data, graphs, calculations, etc…! In all calculations show the set-up with units! If multiple trials are performed, you only need to show the set-up for the first trial.
•
•

•
All data must be recorded to the precision of the instrument. If you are unsure of the precision ask your instructor or refer the Measurements Lab (completed in class). For example, a buret reading where the meniscus falls exactly on 15 mL is recorded as 15.00 mL not 15 mL. The trailing zeros in the 15.00 mL reading are significant! In your calculations use the rules of significant figures to determine how many significant figures your answer should contain. Review the rules for significant figures!
•
LABORATORY CHECK-IN: For this course, you must provide a $20.00 deposit for having a laboratory drawer. If you do not have your deposit on file with the stockroom by the end of the 2nd week of the course, then you will lose access to your drawer and thus be unable to participate in the laboratory sessions. If you drop this course, then you must arrange to check-out with the instructor to secure your deposit. (See the attached page for checking in and out of lab policies

LABORATORY: Chemistry 1C/Rezaie
Since chemistry 1C is an experimental course, the presence of the student in the laboratory is essential for the understanding of the materials covered. A student may be dropped if 2 or more unexcused lab absences are counted. Missed labs cannot be made up unless you have my approval to make up the missed lab by attending an alternate lab meeting. You may miss one lab without penalty. I may allow for emergencies and other complications in life. Required Materials For Lab: 1. Laboratory packet of experiments and exercise for chemistry 1C. Available online at: http://www.foothill.edu/psme/daley/labpackets/1C packet.html 2. Scientific calculator: TI-83, 83-plus,-84 or 86 3. A copy of graphical Analysis software by vernier: supplied by the department for students to copy and return; you do not need to purchase a copy. Also, Graphical Analysis is available on the computers in the PSME Center for students to use. 4. Safety Goggles or Visorgogs: must be purchased from Foothill bookstore. Safety Rules: 1. Make sure you read and understand all of the safety rules. 2. Safety goggles must be worn at all times while working in the chemistry laboratory. NO EXCEPTIONS will be made to this rule. Any student who does not cooperate with this policy will be asked to leave the lab and will receive zero credit for the experiment. Students with prescription glasses will be required to wear safety goggles over their prescription glasses. Contact lenses should NOT be worn in the laboratory. Lab Procedure/Policies: 7

All students are expected to arrive to lab on time and to come to lab prepared to carry out the experiment scheduled for that session. This means that you have studied the experiment for the day, have a basic understanding of its purpose, procedure, and the chemistry involved. Before coming to lab you should do the assigned pre laboratory reading, read the background discussion and procedure and complete the pre laboratory exercises for the experiment. We ask that all students do a conscientious and thorough job cleaning up after themselves, whether it is in their own work area in lab, or shared areas such as the chemical supply table and balance room. When you work with a partner or group of students, you will share the data that is collected. However, you must do your own calculations and lab reports. As a concern for the environment, proper chemical disposal is essential. Students who do not comply with directed procedures may be dropped from the course for repeated offenses. Check with your instructor if you have any questions.
Laboratory Lecture: The beginning of each laboratory session is designated as laboratory lecture period. I will use this period to explain important details of the procedure, calculations, safety hazard and proper chemical disposal. If you are late more than 15 minutes late for lab lecture, you will not be allowed to perform the experiment for that day. Attendance: A student may be dropped when the total unexcused absences for this class exceeds three. These absences include those in which you arrive late for lab lecture and thus not allowed to do the experiment. I will allow for emergencies and other complications in life. Grading: Grading will be based upon: • • • Lab reports/assignments Two lab exams: Qualitative Analysis (unknown Identification) (15% of course grade) (15% of course grade) (5%of course grade)
Lab Tests Lab tests will be based on the laboratory experiments and exercise; and will cover the chemistry, calculations and conclusions of the experiments. Critical thinking is required.
Lab-reports are due one week after the completion of a lab experiment. There will be 10% penalty for late lab reports that are one lab period late. There will be 50% penalty for late reports that are two lab period late. No lab report will be accepted that is more than two lab period late. The lowest lab report will be dropped. 8
Lab Reports Format All your experimental lab reports must follow the following format:
1. TITLE: One line description of the title of the experiment 2. PURPOSE: Brief description of the goal or final outcome of the experiment. 3. INTRODUCTION: This part should consist of a paragraph describing the background
theory, concepts and principles upon which the experiment is based. It may also include statements about importance, relevance and perhaps particular applications of the experiment as well as a discussion of potential sources of errors. 4. EXPERIMENTAL METHOD: In this part you must list all equipment and reagents (with correct name and concentration) that are used in the experiment. You must also provide an experimental procedure outlining all major steps that must be followed to achieve the experiment’s goal. 5. CONCLUSION: This must consist of a brief discussion about the results obtained, whether they are consistent with your expectations and comments on any interesting or unusual observations. 6. ATTACHMENTS: All your experimental data, graphs and answered questions from your lab manual must be attached to this report.
Important Notes: 1. Items 1-5 must be typed. 2. Items 1-4 must be completed prior to the start of each lab. I will initial it before you are allowed to perform the experiment. Detailed guidelines for laboratory report preparation will be given in class. UNKNOWN IDENTIFICATION (5% of course grade): This is based upon the correct identification of the cations in your unknown during the qualitative analysis portion of the lab. You will lose points if you miss a metal cation that is present in your unknown. You will also lose points for false positives. As part of your unknown identification grade, you will be required to submit a flow diagram that accurately summarizes the steps that were required for identification.
CHECK LIST FOR COMPLETED LABORATORY ASSIGNMENTS/REPORTS: • Write your name on the first page. All loose papers must be stapled together! (No paper clips, no bent corners, etc.) Loose papers will not be accepted and if you do turn them in, points will be deducted! The lab report or assignment should be neat. Use pencil or pen. Mistakes during data collection should be crossed out with a single line (not erased!). All writing must be legible. On graphs, circle the points so they can be seen. INCLUDE UNITS on all data, graphs, calculations, etc…! In all calculations show the set-up with units! If multiple trials are performed, you only need to show the set-up for the first trial.

All data must be recorded to the precision of the instrument. If you are unsure of the precision ask your instructor or refer the Measurements Lab (completed in class). For example, a buret reading where the meniscus falls exactly on 15 mL is recorded as 15.00 mL not 15 mL. The trailing zeros in the 15.00 mL reading are significant! In your calculations use the rules of significant figures to determine how many significant figures your answer should contain. Review the rules for significant figures!

LABORATORY CHECK-IN: For this course, you must provide a $20.00 deposit for having a laboratory drawer. If you do not have your deposit on file with the stockroom by the end of the 2nd week of the course, then you will lose access to your drawer and thus be unable to participate in the laboratory sessions. If you drop this course, then you must arrange to check-out with the instructor to secure your deposit. (See the attached page for checking in and out of lab policies
