We have designed the course as an introduction to general chemistry that integrates laboratory explorations with the development of the analytical tools necessary to understand and guide those explorations. Some particular aspects that we will emphasize are.
mathematics as a tool for the exposition and manipulation of chemical concepts. the connection between microscopic models of matter and its macroscopic properties. the connections between applications from pure and applied research and from technology to chemistry Our goal is to help you share in our excitement for and the wonder of science, to challenge you to excel, to give you a sense of empowerment about science, and to encourage you to continue study in scienceand hopefully chemistry. We intend to focus especially on what are the core ideas of chemistry. In the first semester we cover Mahaffy et al., chapters 1 through 8 and chapters 10 and 11. There are 37 MWF lectures and the log below of the lectures as given refers to these lecture numbers.

The laboratory part of the course will let you see first-hand chemical principles and processes in action. It will also give you experience with some of the methods scientists use to do chemical research.
Your laboratory will consist of the following. Measurement of atoms and molecules in solids, liquids and gases.
You will find in experiments the size of atoms and molecules and the empty space between them in solids, liquids and gases. Chemical composition of inorganic salts. By investigating the behavior of different hydrates you will explore the law of fixed chemical composition. You will see that chemical changes can be reversed and learn how to distinguish chemical substances from physical mixtures.
You will also develop the laboratory analysis technique, which allows you to determine in the experiment the molecular formula of the investigated substance and the yield of chemical reactions. Preparation of solutions. This lab experiment will give you an important experience in solutions' preparation using different laboratory techniques: dissolution, dilution and mixing. You will also learn how to use spectroscopic measurements for the concentration control in solutions. Qualitative analysis (2 period lab). In the Qualitative Analysis experiment you will investigate various types of chemical reactions (precipitation, acid-base interaction and complexation) and consider their powerful experimental application for chemical separation and analysis of different ions in a mixture. Chemical thermodynamics: calorimetry (2 period lab).
An experimental method called 'calorimetry' will be used to study heat effects that accompany physical changes and chemical reactions. Lecture workshop on spectroscopy. The goal of this workshop is to use spectroscopic measurements to experimentally determine the relationship between the color, frequency and the wavelength of light. In a series of additional experiments with LEDs the relationship between the energy of a quantum of light and its frequency will be revealed and the value of Planck's constant experimentally determined. Lewis structures and Molecular shapes. Using general concept of Lewis structures and VSEPR method, 3-D shapes of real molecules and their dipole moments will be determined. The lab time will be used to help you in mastering your skills at deducing Lewis structures and became acquainted with various molecular geometries.
Your scores for each part of the course will always be available to you on Blackboard, at We do not assign letter grades to exams, labs, or quizzes. We only assign a course grade. This course grade will be determined based on your overall course score. This score is determined as follows.
For CH101 students, the lab score counts for 20% of your course grade. The various components of the lab will be graded as follows: The lab experiments (30 points for each lab period), lab quizzes (10 points each), pre-lab lecture quizzes (5 points each), and the lab exam (60 points).
Lab quizzes are given at the beginning of each lab to check your familiarity with the basic features of the lab to be done. CH103 (lecture-only) students will graded based on their relative score for the lecture-only part of the course: Lecture exams count as 30/80. 100% = 37.50%, the final exam as 15/80.
100% = 18.75%, lecture quizzes as 10/80. 100% = 12.50%, discussion quizzes as 15/80. 100% = 18.75%, and ALEKS as 10/80. 100% = 12.50%.
No makeup quizzes will be given. A missed discussion quiz counts as 0. The lowest discussion quiz score will be dropped. A missed lecture quiz counts as 0.
The lowest three lecture quiz scores will be dropped. A missed lab counts as 0. The lowest score for the one-period lab experiments will be dropped. The missed two lab period experiment can be made up at the make up lab week at the end of the semester.
If, due to unusual circumstances, such as prolonged illness, you miss more than one lab, please contact Dr. Golger (golger@bu.edu) as soon as possible so that special arrangements can be made to catch up with your work. There are no fixed percentages of A grades, B grades, etc. Rather, we assign course letter grades based on our assessment of how someone should have performed to receive an A, B, etc. Based on past experience, it is likely that the average grade in the course will be in the C+ range.
After each exam we will provide the distribution of overall course scores so far, on a 1000-point scale, and your individual score so far. These overall scores will take into account the scores on the work completed so far (lecture quizzes, discussion quizzes, labs, and exams). In this way, you will have a measure of how you are doing at that point in the course. Any question concerning the grading of a lecture exam, quiz, or laboratory report must be brought to the attention of your discussion or laboratory teaching fellow during the class session in which it is returned to you; material will not be accepted for regrading afterwards. Indicate on the face of the exam, quiz or laboratory report the questions you wish re-graded and your reasons for believing that they were misgraded. The entire work will be re-graded.

Be sure you have made no alterations in your work. We occasionally photocopy your graded work as a check. Please note that the penalties for academic misconduct are severe, as detailed in Boston University's Academic Conduct Code, CH101 is prerequisite to CH102. To continue to CH102, a grade of at least C- in CH101 is required. Learning chemistry requires persistence, diligence and hard work. We suggest that you plan to spend about 15 hours per week on this course over and above the scheduled class contact hours.
If you are willing to devote this time, and you spend it wisely and effectively, you will be able to perform your best. In an effort to provide some more specific guidance, we offer detailed suggestions The teaching staff will hold office hours throughout each week. These and many others resources are detailed If you are experiencing difficulty, please come to see your lecture professor or Professor Golger without delay. Often, students in this course perceive that they are doing poorer work than they actually are. Particularly for first-year students, we recognize that it may be difficult for you to judge your academic standing in the course, since we do not use the same type of grading scheme with which you may be familiar from high school. That is why it is important for you to speak to us before making any major decision, such as dropping the course. If dropping the course appears to be in your best interest, we still would like to work through the decision with you.
We are also happy to advise you on appropriate choices for your academic program. If you drop the course by Tuesday, October 10, no record of it will appear on your transcript. After that date, until the end of the day Friday, November 10, you may drop the course but with a W grade (withdrawn). If you must drop the course, note that CH101 will be given during the Spring and Summer sessions of 2017.
