Matter SubstancesMixtures Elements Compounds Heterogeneous Mixtures Homogeneous Mixtures Mixtures Substances separated by physical methods Compounds Substances separated by chemical methods
Mixtures Combo of 2 or more pure substances Physically combined NOT chemically combined Each substance retains its own identity and properties
Mixtures Variable composition No unique properties Ex: sugar and sand mixed together physical methodsSeparated by physical methods May be homogeneous or heterogeneous
Types of Mixtures Heterogeneous: See boundary or regions that look different Ex: colloids suspensions ice water granite cereals
Colloid: milk Suspension: smoke/smog Heterogeneous mixture: ice water Heterogeneous mixtures: cereal/granite
Homogeneous: constant composition throughout, single phase Ex: Solutions (all 3 phases) Air Windex kool-aid
Air Homogeneous Solutions: Drink mix Window cleaner
Hints for Mixtures Solutions (gas & liquid phases) transmit light No particles big enough to scatter light Look translucent (see-through) Suspensions look cloudy – scatter light Particles big enough to scatter light Settle upon standing
Where does this liquid fit? Homogeneous? Heterogeneous?
Particle Diagrams Atoms only: monatomic element Molecules: diatomic element
Particle Diagrams Molecules: triatomic compound Mixture: monatomic element diatomic element triatomic compound
Conservation of Mass Mass before = Mass after # atoms before = # atoms after
Separating Mixtures Physically combined Separation based on physical properties –Sorting: Appearance –Filtration: Size –Distillation: Boiling Point –Crystallization: Solubility –Magnet: Magnetization –Chromatography: “Travel” ability
Filter: Solid particles can be separated from liquid
Distillation Used to separate liquids with different boiling points
Paper Chromatograhy Can separate liquids with different solubilities
Crystallization Can separate solids dissolved in liquids
September 9, 2009 Obj – Differentiate between various forms of matter.
1 & Mr. ShieldsRegents Chemistry U03 L07 2 Mixtures A Combination of 2 or more pure substances. (What’s the definition of a pure substance?) notIn Mixtures,
Pure substance Only one kind of material
Mixtures Mr. Skirbst Physical Science Topic Classes of Matter.
Topic: Classifying Matter
Chapter 4 Notes Mixtures & Solutions.
Chapter 1: The Nature of Science. What is Science? Life, Earth and Physical Science Living things Earth and Space Matter and Energy Chemistry Physics.
IMPURE SUBSTANCES: MIXTURES
Elements, Compounds & Mixtures
1. What are two properties used to describe matter?
Classification of Matter
Pure Substances & Mixtures. What is a pure substance ?
Pure Substances & Mixtures
What is Matter? (Part 1 – Glencoe chapter 18-1). I. Chemistry The study of matter and how it changes Differences in material properties relate to what.
Physical Property Describes form or behavior of matter.
Mixtures of Matter. Classification of Matter.
Classifying Matter Mixtures, Elements and Compounds.
Introduction to Matter. All Matter Has Three Major Characteristics: G 1. It has mass G 2. It occupies space G 3. It is made of particles (atoms) G 1.
Matter Has Mass and Takes Up Space. Mixture Varying composition Varying composition Not Chemically Combined Not Chemically Combined Retain properties.
