Across
  1. 2. = substance made from atoms of two or more elements that are chemically bonded such as water or salt
  2. 4. = matter with constant composition. all particles have the same properties
  3. 7. properties = describe a behavior of matter; change as a result of contact with other matter or the influence of energy
  4. 8. substance = made of only one type of matter (elements or compounds)
  5. 10. = measure of the amount of space that is occupied (a three dimensional value such as cm^3 or mL)
  6. 12. = beginning substances that start a reaction
  7. 13. = physical blend of matter
  8. 14. mixture = only 1 visible distinct phase, the phase has the same properties throughout
Down
  1. 1. mixture = 2 or more visibly distinct phases, each phase has very different properties. uneven distribution of substances
  2. 3. properties = a property that can be observed and measured without changing the material's composition
  3. 5. = a substance made up if atoms with the same atomic number
  4. 6. change = the composition of matter always changes
  5. 9. mixtures = distillation, filtration, chromatography, evaporation
  6. 11. = anything with mass and occupies space
  7. 13. = measure of the amount of matter
