Here ate today’s CHM 100 notes. These notes cover conservation of mass (from Chapter 3), and some Chapter 4 topics: Dalton’s atomic theory, the nuclear model of the atom, atomic terms, kinds of elements (metals/nonmetals/metalloids) , and the periodic table.
(I’ve included a page in these notes marking where the material for the first test ends.)

Here are today’s CHM 100 notes. These notes cover scientific notation, the kinetic picture of matter, phases and phase changes, chemical/physical properties and changes, mixtures/pure substances, and conservation of mass. (Conservation of mass will be discussed in the next class period, but I pit it here so all the chapter three stuff would be in one place.)

Here ate the notes from today’s CHM 100 class. These notes cover significant figures – how to determine significant figures in a measurements and how to calculate wih significant figures. Exact numbers (for unit conversions, etc.) are also discussed.

Here are the notes for today’s CHM 100 class. These notes start with density – its units and how to measure it.
The notes also cover dimensional analysis (aka the “drag-and-drop” method) and its use for metric unit conversions – along with example problems.
The last page introduces the definitions of accuracy and precision for measured numbers.

Here are the notes for today’s CHM 100 class. These notes cover the scientific method (including hypothesis, theory, and law). They also introduce the metric system’s base units, prefixes, and the derived unit for volume.
