Mixtures Mr. Skirbst Physical Science Topic 11
4 Classes of Matter
1. Mixtures 2. Solutions 3. Elements 4. Compounds
Mixtures A combination of two or more substances mixed together but not chemically combined
Properties of Mixtures Substances keep identity No new substances formed No fixed proportions Can be physically separated
2 Types of Mixtures 1.Heterogeneous - different throughout - least mixed mixture (ex. Tossed salad)
2 Types of Mixtures 2.Homogeneous - same throughout - well-mixed mixture (ex. milk)
Homogeneous Mixtures Colloid - particles are mixed, but not dissolved Solution - particles are dissolved
Solutions Homogeneous mixture formed when one substance dissolves in another
Solutions Solute – substance that IS dissolved Solvent – substance that DOES the dissolving Solubility – substance’s ABILITY to dissolve
Lab Techniques Decanting– separating liquids + solids by pouring off liquid Filtering– separating liquids + solids by passing through a filter (semi-permeable membrane)
Matter and Mixtures. Types of Matter Elements –Simplest of Substances –Made of only one type of atom –118 Known.
Mixtures. A mixture is a combination of two or more substances where there is no chemical combination or reaction.
Example of Physical Change Example of Chemical Change.
MATTER PURE SUBSTANCE ELEMENTCOMPOUND MIXTURE HOMOGENEOUS SOLUTION COLLOID HETEROGENEOUS SUSPENSION.
Classifying Matter. Classifying a substance by physical properties (state, boiling point, color, density…) is not specific enough –one substance can exist.
Substances, Compounds & Mixtures How everything is put together.
Classifying Matter Science 8 Mrs. Marks. Based on the Makeup of Matter Pure Substances –Elements –Compounds Mixtures.
CHAPTER 15: CLASSIFICATION OF MATTER. COMPOSITION OF MATTER Matter can exist as: Substance: Type of matter with a fixed composition; can be element or.
Mr. Chapman Chemistry 30. What is a solution? A solution is a mixture or a combination of two or more things. A solution is also known as a homogeneous.

Classification of Matter Section 1.1 Composition of Matter.
What’s the Matter Game Definitions Unit 2: Classification of Matter Physical Science Steinbrink.
Seconds Left: If there only about 100 types of elements in the world, why are there.
Mixtures. 2 or more substances that are NOT chemically combined Examples: Pizza, Fruit salad, juice No chemical change Each substance in a mixture keeps.
Substances, Mixtures, and Solubility Chapter 21. What is a solution? O Substance – matter that has the same fixed composition and properties O Cannot.
Classifying Matter 2.2. Pure Substances A pure substance is matter that always has exactly the same composition. A pure substance is matter that always.
Matter: Anything that has mass and takes up space All matter is made up of tiny particles called atoms Matter is classified as either an element, compound,
Mixtures and Compounds. Composition of Matter One way we classify matter is either pure substances or mixtures. Pure substances are either elements or.
Chem 11. Indications of a chemical reaction Energy absorbed or released Color change Gas produced Precipitate- solid that separates from solution Not.
CLASSIFICATION OF MATTER. Pure Substances: Contain only 1 type of material Cannot be separated by physical means (filtration, etc.) Mixtures: Elements:

Physical Science Unit Overview: Chapter 7 – Types of Matter Lesson 1 – Properties of Matter Lesson 2 – Elements Lesson 3 – Classifying Elements Lesson.
Matter exists as either a pure substance or a mixture. Section 1: Composition of Matter K What I Know W What I Want to Find Out L What I Learned.
Matter. “Food Matters” Is it a Pure Substance or a Mixture? Matter can be divided into two main categories: – Pure substances are homogeneous throughout.
Compounds revisited: A substance composed of two or more elements that are chemically combined.
Exploring Matter Topic 1. Safety Symbols Symbol Shapes: These shapes and their colours indicate how dangerous a substance is.
Pure Substances Mixtures. Everything that has mass and volume is called matter.
Matter Pure Substances Mixtures Elements CompoundsHeterogenousHomogenous.
Chapter 2 Properties of Matter. Elements An element is a substance that cannot be broken down into simpler substances. GoldAluminumCarbonIodine.
Pure Substances & Mixtures. What is a pure substance ?
States of Matter Solid Solids – shape and volume don’t change (definite or fixed) Liquids – volume doesn’t change but takes shape of container Gas – takes.
Separation Methods. Types of Solutions & Mixtures Solution: A homogeneous mixture of two or more compounds where a solute has dissolved in a solvent Solution:
Lesson 12: What Happens When Substances are Mixed with Water? Key Terms.
Compounds, Mixtures and Solutions Compounds A pure substance composed of two or more elements that are chemically combines Involves a chemical change Each.
Mixtures 2 or more substances mixed together but not chemically combined Air is a mixture.
Chapter 4 Notes Mixtures & Solutions. Matter Pure Substance (uniform composition) Mixture (variable composition) Elements (only one kind of atom) Compounds.
Separating Mixtures Unit 1: Measurement & Matter.
Matter is divided into 2 groups: ◦ Pure substances- made of only 1 type of particle ◦ Mixtures - made of at least 2 types of particles.
Pure Substances Cannot be broken down into simpler substances and still have the same properties.
Compounds / Mixtures. Compounds A compound is composed of two or more elements that are chemically combined. CompoundElements combined SugarCarbon, hydrogen.
Terms on phase changes: ___1. Boiling point ___1. Boiling point ___2. Melting point ___2. Melting point ___3. Vaporization point ___3. Vaporization point.
MATTER Anything that has mass and takes up space (volume) HETEROGENEOUS Mixture whose parts are unevenly distributed; you can see the different parts easily.
Types of Mixtures. They are substances held together by physical forces, not chemical and are not chemically combined. This mean a mixture will keep it’s.
Mixtures and Solutions. A mixture is a combination of two or more components that are NOT chemically combined, and retain their identities. Mixtures can.
