Matter PURE SUBSTANCES AND MIXTURES
Matter Chemistry is the study of the composition of matter and the changes matter undergoes. Matter – anything that has mass and occupies space Examples: Table You Air
Matter can be divided into two smaller subgroups: Pure substances Matter Mixtures Pure Substances
Pure Substances Pure substances are broken into two smaller subcategories: Matter COMPOUNDS ELEMENTS Mixtures Pure Substances Compounds Elements
Element - simplest form of matter that has a unique set of properties. Elements are composed of ONE type of atom or molecule. Elements cannot be broken down into smaller substances. They are what they are! Gold (Au), Silver (Ag), Carbon (C), Oxygen (O 2) – each individual element
Compound - substance that contains two or more elements chemically bound together in a fixed proportion. CO 2, H 2 O, C 6 H 12 O 6 – More than one element
Compounds can be broken down into their components (ELEMENTS) by CHEMICAL means, but NOT physical. C 6 H 12 O 6 (+ Heat) H 2 O + Carbon H 2 O (+ Electricity) H 2 + O 2 BOLD = COMPOUND The properties of compounds are quite different from those of their component elements. Matter Mixtures Pure Substances Compounds Elements Can be separated CHEMICALLY
Mixtures The second large subgroup of matter are mixtures. Mixtures are composed of two or more elements or compounds physically combined. Mixtures can be separated PHYSICALLY into their components (PURE SUBSTANCES). Examples: Sugar and Water, Pasta and Water, M&M’s & Skittles. Matter Mixtures Can be separated PHYSICALLY Compounds Pure Substances Elements
Mixtures Two different types of mixtures: Heterogeneous Matter Homogeneous Mixtures Heterogeneous Can be separated PHYSICALLY Homogeneous Pure Substances Compounds Elements Can be separated CHEMICALLY
Heterogeneous Mixtures Heterogeneous mixtures composition that is NOT uniform throughout. You can see things in there! Chicken Noodle soup, dirt from your backyard, Sand in water, Concrete You would be able to physically pick apart the components of a heterogeneous mixture
Homogeneous Mixtures Homogeneous mixtures uniform composition. Same composition of elements or compounds throughout. Also Air, called solutions. Salt in Water (OCEANS!), Sugar in Water (Kool-aid)
