Different Physical Property Technique Boiling point Distillation State of matter (solid/liquid/gas) Filtration Adherence to a surface Chromatography Volatility Evaporation Density Centrifugation and decanting Separation of Mixtures • Separate mixtures based on different physical properties of the components. • Physical change.

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. Tro's "Introductory Chemistry", Chapter 3
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. Tro's "Introductory Chemistry", Chapter 3
Practice—A Student Places Table Sugar and Sulfuric Acid into a Beaker and Gets a Total Mass of 144.0 g. Shortly, a Reaction Starts that Produces a “Snake” of Carbon Extending from the Beaker and Steam Is Seen Escaping. If the Carbon Snake and Beaker at the End Have a Total Mass of 129.6 g, How Much Steam Was Produced? Tro's "Introductory Chemistry", Chapter 3
