  1. Pure Substance vs. Mixtures

  2. Matter can be a “PURE” substance or a “MIXTURE” • Pure Substance • Element • Compound • Mixture • Homogeneous • Heterogeneous

  3. Compounds Can be decomposed into simpler substances by chemical changes, always in a definite ratio, Molecules Carbon Dioxide, CO2 Water, H2O Elements Cannot be decomposed into simpler substances by chemical changes, Atoms Gold, Au Sodium, Na What is a pure substance?

  4. What is a pure substance? • ELEMENTS • Individual Elements represent individual Atoms • COMPOUNDS • Compounds are Molecules • Molecules are made up of two or more atoms.

  5. What is a mixture? Mixtures are two or more substances that are NOT chemically combined. Mixtures can be either Homogeneous or Heterogeneous

  6. Homogenous Mixtures Homogenous mixtures look the same throughout and particles are too small to be seen. Examples: cake mix, yogurt

  7. Heterogenous Mixtures Heterogeneous mixtures are not evenly distributed and composed of large pieces that are easily seen and separated. Example: Party Mix, Bowl of Cereal
