MATTER WHAT IS MATTER? v IS ANYTHING THAT OCCUPIES SPACE AND HAS MASS v MATTER IS EVERYTHING IN THE UNIVERSE CLASSIFICATION OF MATTER PURE SUBSTANCE MIXTURE Ø element Ø homogeneous Ø compound Øheterogeneous  WHAT IS THE DIFFERENCE BETWEEN MIXTURE AND PURE SUBSTANCE? PURE SUBSTANCE MIXTURE constant composition proportions of components may vary. Ex. Juice /Milk tea /SB fixed set of properties Ex. Water and Hydrogen peroxide/ Vit. C/ properties vary with cannot be separated into composition Ex. Solubility/ Silver ring simpler substances (for can be physically separated Elements) into two or more pure substance Pyrite= iron sulfide (FeS2) Gold= Au PURE SUBSTANCE  CLASSIFICATION OF PURE SUBSTANCE ELEMENT COMPOUND Ø simplest substance Ø two or more elements are chemically bonded. Ø cannot be chemically Ø can be chemically subdivided into simpler subdivided into simpler substances substances Ø products are either elements or simpler compounds ELEMENT COMPOUND ELEMENTS METAL NON-METAL METALLOID MIXTURE  WHAT IS MIXTURE? Ø combination of two or more pure substances ØEx. Compound + Compound H20 + NaCl Salt Solution TWO TYPES OF MIXTURE HOMOGENEOUS HETEROGENEOUS mixture that has a mixture in which the uniform appearance properties and and the same appearance are not properties uniform throughout throughout  SOLUTION TRANSPARENT APPEARANCE LIGHT CAN PASSED THROUGH OIL AND WATER (HETEROGENEOUS) CEREAL IN MILK (HETEROGENEOUS) SUSPENSION AND COLLOIDS SEPARATION METHOD method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures. FILTRATION DISTILATION PROCESS
