Week One Notes CHAPTER ONE Chemistry— Study of matter, its composition, properties, its chemical and physical reactions, and the energy associated with these changes. Matter — mass and volume. Co mposition— types and amounts of simpler substances. Physical Properties— color, melting point, density, hardness. Chemical Properties— flammability, corrosiveness, acid/base, oxidizing Classification Matter = Pure substance 1) Element Compound Mixture 1) Homogenous/Heterogeneous (*depends on scale*) Extensive Property— mass, volume, length Intensive Property— color, viscosity, melting point, boiling point, ductility, malleability, density Density— (Mass)/(Volume) *mass is determined by a balance and volume is determined by displacement SI Units Mass, kilogram, kg Length, meter, m
