Inorganic AND ORGANIC Chemistry
STRUCTURES,COMPOSITION,PROPERT
IES AND REACTION
Chemistry the study of the composition, structure, properties, and reactions of matter.
Organic Chemistry the study of the structures that contain the element carbon
Inorganic Chemistry the study of all other substances except those that contain the element
carbon
Geochemistry the study of the chemical composition of ores, soils, and minerals of the surface
of earth and other planets
Measured numbers are numbers you obtain when you measure a quantity
Exact numbersare numbers obtained by counting items
Density formula D=m/v
Chemical a substance that always has the same composition and properties wherever it is
found
Matter anything that has mass and occupies space
Pure substance matter that has a fixed or definite composition
Element composed of only one type of material
Compund consists of two or more elements always chemically combined in the same
proportion
Mixture two or more substances are physically mixed, but not chemically combined
Homogeneous mixtures are not visible
Heterogeneous mixtures are visible
Solid definite shape and volume, particles close together in fixed arrangement, particles move
slowly
Liquid definite volume, but not definite shape, particles move randomly in all direction, same
shape as container
