This document provides information about General Chemistry 1, including contact information for the instructor, Dr. Mark B. Mitchell, and resources for students. It outlines the course structure, which includes Monday and Wednesday classes, Friday peer-led sessions, and exams on Mondays and Wednesdays. The document also gives a brief introduction to chemistry, covering topics like the definitions of matter and physical and chemical properties and changes. It defines elements, compounds, mixtures, and the three states of matter. Finally, it discusses the importance of energy in chemistry and how energy is conserved in chemical and physical changes.

14. SYLLABUS

15. CHEMISTRY The Study of the Nature of Matter and Change Matter – anything that has mass and takes up volume Examples of non-matter things? Change refers to a change in properties – characteristics - of a substance.

17. Color

18. Melting point

19. Electrical conductivity

20. Density

23. Classifications of Matter Substance – Chemically the same throughout Element – Cannot be broken down into simpler substances by chemical means Compound – Chemical combination of two or more elements. All portions contain the same elements in the same proportions Mixtures – Can be separated into two or more substances by physical means Heterogeneous mixture – non-uniform mixture Homogeneous mixture – uniform mixture

24. Three States of Matter Solid – has a fixed shape Liquid – takes on the shape of the container, but fills the container only to the volume of the liquid; a liquid/gas interface will be formed. Gas – takes on the shape of the container, and fills the container completely.

27. Two kinds of energy

28. Kinetic energy – the energy of motion – ½ mv2

29. Potential energy - energy that depends on position
