  1. 5. A combination of chemical symbols and numbers to represent a pure substance (H2O: water, CO2: carbon dioxide, C6H12O6: glucose, NaCl: table salt)
  2. 6. A pure substance made of only one kind of atom
  3. 7. light, heat, sound, force, electricity
  4. 10. a method used to separate insoluble solids from liquids.
  5. 11. the amount of matter in an object (g)
  6. 12. building blocks of living and non-living matter
  7. 14. A substance made up of atoms of two or more DIFFERENT elements bonded together
  8. 15. two or more types of matter that interact but no new substances are formed
  9. 16. the amount of matter in a given space d=m/v (how compact the atoms are in a given volume) - specific physical property for every type of substance
Down
  1. 1. a mixture in which you can see the different parts and are more easy to separate
  2. 2. any type of matter (solid, liquid, gas, plasma) made of atoms that has a specific density (examples: brass, water, aluminum, pine, PVC, copper, nylon, hydrochloric acid, rust)
  3. 3. Mixture that is the same throughout. and are more difficult to separate
  4. 4. A technique that is used to separate the substances of a mixture based on the tendency of each component to travel up filter paper using water or another solvent
  5. 5. a separation technique that produces pure solid particles of a substance from a solution that contains the dissolved substance
  6. 7. process that can be used to evaporate a liquid from a mixture and leave the solid
  7. 8. anything that has mass (g) and takes up space (volume) - solid, liquid, gas, plasma
  8. 9. A substance made of only one kind of matter and having definite properties (atoms, elements, molecules, compounds)
  9. 13. The amount of space an object takes up (centimeters cubed)
