General Chemistry I

Open, Lecture—Fall

Chemistry is the study of the properties, composition, and transformation of matter. Chemistry is central to the production of the materials required for modern life; for instance, the synthesis of pharmaceuticals to treat disease, the manufacture of fertilizers and pesticides required to feed an ever-growing population, and the development of efficient and environmentally benign energy sources. This course provides an introduction to the fundamental concepts of modern chemistry. We will begin by examining the structure and properties of atoms, which are the building blocks of the elements—the simplest substances in the material world around us. We will then explore how atoms of different elements can bond with each other to form an infinite variety of more complex substances called compounds. This will lead us to an investigation of several classes of chemical reactions, the processes by which substances are transformed into new materials with different physical properties. Along the way, we will learn how and why the three states of matter (solids, liquids, and gases) differ from one another and how energy may be either produced or consumed by chemical reactions. In weekly laboratory sessions, we will perform experiments to illustrate and test the theories presented in the lecture part of the course. These experiments will also serve to develop practical skills in both synthetic and analytic chemical techniques.
