  1. Chapter #3 Matter

  2. Matter • Anything occupying space and having mass. • Matter exists in three states. • Solid • Liquid • Gas • Plasma

  3. Chemical Change Electrolysis of Water H2O H2(g) + O2 (g)

  4. Different Physical Property Technique Boiling point Distillation State of matter (solid/liquid/gas) Filtration Adherence to a surface Chromatography Volatility Evaporation Mixture Separation Mixtures can be separated based on different physical properties of the components.

  5. Mixture Separation Distillation of a Solution Consisting of Salt Dissolved in Water

  6. Filtration Separates a liquid from a solid.

  7. Law of Conservation of Mass • Antoine Lavoisier • “Matter is neither created nor destroyed in a chemical reaction.” • The total amount of matter present before a chemical reaction is always the same as the total amount after. • The total mass of all the reactants is equal to the total mass of all the products.

  8. Conservation of Mass • Total amount of matter remains constant in a chemical reaction. • 58 grams of butane burns in 208 grams of oxygen to form 176 grams of carbon dioxide and 90 grams of water. butane + oxygen  carbon dioxide + water 58 grams + 208 grams  176 grams + 90 grams 266 grams = 266 grams
