  1. How many chains are there in the C.O.M, what are they and what is in them?
    • There are 2
    • #1 includes
    • mixtures
    • mechanical mixtures+Solutions
    • Ordinary mechanical mixtures+suspensions+colloids
    • #2
    • Pure substances
    • Elements+Compounds
  2. What is the difference between a homogeneous and heterogeneous mixture?
    homogeneous: looks the same throughout ( 1 phase)

    heterogeneous: does not look the same throughout (2 or more phases)
  3. Define Mixtures
    (and is it Heterogeneous or homogeneous?)
    • *Made of two or more kinds of molecules (particles)
    • Heterogeneous
  4. Mechanical mixtures (htg or hmg)
    • *Different visual Particles
    • *ex. pizza
    • heterogenous
  5. Solutions (htg or hmg)
    • *Different particles
    • *Too small to see even with a microscope
    • ex. salt water
    • Homogeneous
  6. Ordinary Mechanical mixtures
    • *easy to see different parts
    • *ex. bread,eggs
    • Heterogeneous
  7. Suspensions
    • *solid particles that eventually settle out
    • *ex. Pond water, raw milk
    • Heterogeneous
  8. Colloids
    • *very small particles that do not settle out but they do scatter
    • ex. homo milk
    • jello
    • Heterogeneous
  9. Pure Sunstances
    • * made of one kind of atom or molecule
    • Homogeneous
  10. Elements(atoms)
    • *Appear on the periodic table
    • ex. hydgen
    • Homogeneous
  11. Compounds(molecules)
    • *Combinations of elements
    • ex. H2O
