Physical properties or changes: observed without the makeup of the sample changing. (phase change, break)

Chemical properties or changes: the makeup of the sample changes to a different substance. (rust, burn)

Mixture: different substances physically mixed together. Can be separated based on physical property differences: Density: oil and water Particle size: a screen or sieve: rocks and sand Solubility: sand and salt

Boiling point: distillation : alcohol and water

Homogeneous vs heterogeneous: uniformity or not in makeup. Salt water vs salad

Element: simplest form of matter. A pure substance. Oxygen or hydrogen Compound: Two or more elements CHEMICALLY bonded together. A pure substance. Water only separated into H and O when chemical bonds broken. A mixture is NOT a pure substance (separated by physical differences).

Homework: 1) Add the question sections to your Cornell notes for what we did today. 2) Write the summary section for all of the Cornell notes on this topic.

Law of definite proportions A compound is always composed of the same elements in the same proportion by mass (regardless of the sample size). Calculate percent by mass for each element. Every sample of same compound will have the same percents by mass.

Law of Multiple Proportions Get mass ratio of each compound mass of element A / mass of element B Get ratio of the two mass ratios This will be a whole number

Homework: Chemistry: Answer questions 31 – 63 (ODD ONLY) at end of Chapter three. Chem Com: Answer questions page 43.
