  19. Pure Substances and Mixtures

  20. Today’s Game Plan

  21. 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.

  22. 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

  23. Examples of Elements: • Hydrogen • Carbon • Lithium • Gold What are two other examples of elements not listed above? What do all elements have in common?

  24. Compound • Definition: substance formed by the chemical combination of two or more elements • can be broken into simpler substances by a chemical change + = Compound

  25. 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.

  26. More Examples of Compounds

  27. 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

  28. 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

  29. Heterogeneous Mixtures • variable appearance and composition

  30. Today’s Game Plan

  31. Raise ‘em Up! • Look at the following example and with your partner determine if it is a heterogeneous mixture, homogeneous mixture, element, or compound

  32. Chicken Noodle Soup

  33. Pure Water

  34. Tap Water

  35. Pure Gold

  36. Coca-Cola

  37. Today’s Game Plan

  38. Kool Aid has mass and takes up space

  39. Can be separated by allowing water to evaporate

  40. Same composition throughout

  41. 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.
