Pure Substances • Composition is the same throughout and does not vary from sample to sample. • CANNOT be broken down by physical changes • Can be an element or compound.
Element • Definition: substances in their simplest forms • Cannot be broken down by a physical or chemical change • Found on the periodic table • Made up of one type of atom
Examples of Elements: • Hydrogen • Carbon • Lithium • Gold What are two other examples of elements not listed above? What do all elements have in common?
Compound • Definition: substance formed by the chemical combination of two or more elements • can be broken into simpler substances by a chemical change + = Compound
Law of Definite Proportions • Acompound is always composed of the same elements in the same proportions. In other words, Carbon Dioxide (CO2) is always composed of 1 atom of C and 2 atoms of O. If there are different amounts of carbon or oxygen, it is no longer carbon dioxide.
Mixture • Definition: two or more pure substances (elements or compounds) that are mixed together but NOT joined chemically • NOT a pure substance • Examples: The air we breath, gasoline for cars, the sidewalk on which we walk
Homogeneous Mixtures • Uniform in composition and appearance • Same proportion of components throughout • Consists of two or more substances in the same phase • Also called solutions
Heterogeneous Mixtures • variable appearance and composition
Raise ‘em Up! • Look at the following example and with your partner determine if it is a heterogeneous mixture, homogeneous mixture, element, or compound
Go with the Flow…Chart • With your partner, look at the example on the board. Fill out the blank matter chart to determine the matter’s classification.
