  6. 14. SuperAtom
  7. 15. of a substance is the ratio of the mass of a sample of the substance to its volume.
  8. 18. refers to whether a compound will react with water or air (chemically stable substances will not react).

  14. 33. property Any characteristic of matter that depends on the amount of matter being measured
  15. 35. A chemical substance that is made up of a particular kind of atom and cannot be broken down or transformed by a chemical reaction.
  16. 36. the process typically involves heating the mixture until no more liquid remains,

  1. 1. standards fixed by international agreement in the International System of Units
  2. 2. Chemistry The study of compounds not covered by organic chemistry.
  3. 3. is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.
  4. 5. If a number has a decimal Present, use the
  5. 6. Chemistry The study of the chemistry of matter and the development of tools to measure properties of matter.
  6. 7. property Any characteristic that can be determined only by changing a substance’s molecular structure.
  7. 9. The initial units of the metric system, which eventually evolved into the SI system, were established in
  8. 13. change A process that causes a substance to change into a new substance with a new chemical formula.
