Basic Elements
99% of all living things are:
Sulfur (S)Carbon (C) Hydrogen (H)Nitrogen (N)Oxygen (O)Phosphorus (P)

Chemistry and Life
ORGANIC moleculesAnything that contains Carbon (C)Ex. Sugar (C6H12O6)
All Living Things (animals, plants, etc.)
INORGANIC moleculesDo NOT contain carbonEx. H2O, O2
Atmosphere, Rocks, Waste products

Acids and Bases
Measured as pHOn a scale from 1-14pH = a measure of the number of hydrogen atoms
Substances that are very acidic or very basic are dangerous to living things

Density
Amount of matter in any given space
Density = Mass / Volume

Solutions
Mixture of two or more substances
Solvent = does the dissolving (ex. Water)
Solute = is dissolved (ex. Salt)
