  1. 5. property Any characteristic that can be determined without changing the substance’s chemical identity.
  2. 6. property Any characteristic of matter that does not depend on the amount of the substance present.
  3. 12. Any of several attractive forces that serve to bind atoms together to form molecules

  7. 18. the most common state of matter in the universe
  8. 20. the branch of science that deals with the identification of the substances of which matter is composed
  9. 22. Chemistry The study of compounds not covered by organic chemistry.
  10. 23. is composed of one type of atom or molecule.
  11. 25. property Any characteristic of matter that depends on the amount of matter being measured
  12. 27. is composed of different types of atoms or molecules that are not chemically bonded.
  13. 28. SuperAtom
  14. 29. Particle are loosely packed
  15. 30. 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.
  16. 32. The standard unit of length in both the SI and original metric systems is the
  17. 33. If a number has no decimal (the decimal is Absent)
  18. 34. the adhesion of a chemical species onto a surface
  19. 35. property Any characteristic that can be determined only by changing a substance’s molecular structure.
  20. 36. standards fixed by international agreement in the International System of Units
  21. 37. reactioncA process involving the breaking or making of interatomic bonds and the transformation of a substance (or substances) into another.
  22. 39. If a number has a decimal Present, use the
  23. 40. The study of chemical processes that occur inside of living organisms.
  24. 44. refers to whether a compound will burn when exposed to flame.
  25. 45. is a mixture of two or more chemical substances where the various components can be visually distinguished.
  26. 46. is the measure of the amount of space occupied by an object.

  1. 1. The SI base unit of time is the
  2. 2. The SI unit of temperature is the
  3. 3. The standard volume is a
  4. 4. refers to whether a compound will react with water or air (chemically stable substances will not react).
  5. 7. A chemical substance that is made up of a particular kind of atom and cannot be broken down or transformed by a chemical reaction.
  6. 8. is a type of mixture in which the composition is uniform and every part of the solution has the same properties.
  7. 9. change A process that causes a substance to change into a new substance with a new chemical formula.
  8. 10. is a purification process where the components of a liquid mixture are vaporized and then condensed and isolated. In simple distillation, a mixture is heated and the most volatile component vaporizes at the lowest temperature.
  9. 11. standard of comparison for measurements
  10. 13. the process typically involves heating the mixture until no more liquid remains,
  11. 14. The initial units of the metric system, which eventually evolved into the SI system, were established in
  12. 19. the temperature at which a substance boils
  13. 21. Chemistry The study of the chemistry of matter and the development of tools to measure properties of matter.
  14. 23. is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates.
  15. 24. The “ingredients” of a reaction are called
  16. 26. are any non-zero digits or trapped zeros.

  18. 32. Something that consists of diverse, non-bonded elements or molecules.
  19. 38. The standard unit of mass in the SI system is the
  20. 39. Chemistry The branch of chemistry that applies physics to the study of chemistry
  21. 41. A substance made from two or more elements. Consists of a fixed ratio of chemically bonded atoms. Has unique properties that are different from the properties of its individual elements.
  22. 42. the temperature at which a substance melts
  23. 43. of a substance is the ratio of the mass of a sample of the substance to its volume.
