Presentation transcript:

Welcome to GENERAL Chemistry! CHM 108, Dr. Davis Index Cards Name (preferred name) Major Year Describe your previous experience with chemistry A previous skill you’ve learned by doing (e.g., sport, musical instrument, etc.) Any questions or concerns about this class?

What is chemistry?

?? What is the difference between an atom and a molecule? Anything that has mass and occupies space Chemistry is understanding behavior of matter by understanding the behavior of atoms and molecules Air around us is matter! What chemical components make up air? Oxygen (O2) Nitrogen (N2) Carbon dioxide (CO2) Carbon Monoxide (CO) Argon (Ar) ?? What is the difference between an atom and a molecule?

Is it possible to be “chemical free”?
