Classification of Matter

We break matter up into…

Separation of Matter Mixtures Pure Substances Can be separated by PHYSICAL means Separation doesn’t chemically alter the components in the mixture EXA - Iron filings and salt (magnet OR dissolve + filter) Pure Substances Can be separated by CHEMICAL means only. EXA - electrolysis of water

Heterogeneous Mixture Speckled, Chunky, Uneven Cloudy to opaque Fluid mixtures settle into layers Solids in fluids can be filtered out Can be separated by PHYSICAL MEANS EXA - Iron Filings in salt (can be solids, liquids, or gasses)

Homogeneous Mixture (Solutions) Look uniform Transparent Can’t be filtered Can be separated by PHYSICAL means EXA - Saltwater (distillation) (can be solids, liquids, or gasses) ***If the concentration can vary, it’s a solution!

Elements Resist decomposition Smallest indivisible component that retains the characteristics of the substance (can’t be broken down!) EXA - Hydrogen, Carbon, Gold (can be solids, liquids, or gasses)

Compounds A chemical combination of elements (the elements exist in specific ratios) Can be broken down by CHEMICAL means (but it will no longer retain the same properties) EXA - Electrolysis of Water (Hydrogen + Oxygen) (can be solids, liquids, or gasses) (Click image to see a short clip)

Elements and Compounds Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions. Examples of elements: iron (Fe), copper (Cu), hydrogen (H) and oxygen (O2). Examples of compounds: water (H2O) and salt (Sodium Chloride - NaCl).

Electrolysis of Water Water is wet, clear, doesn’t burn… What comes out of the electrolysis of water is flammable, a clear gas and is CLEARLY no longer water!
