  1. 3. Occurs when a substance is converted to a new substance
  2. 10. Any substance that has mass and takes up space by having volume
  3. 12. is a system in which an ordinary decimal number is expressed as the product of a number between 1 and 10 times 10 raised to a power; expressed as N x 10n

  11. 29. The phase transition in which liquid turns to solid
  12. 31. The study of chemical processes that occur inside of living organisms

  1. 1. A process in which a conversion factor written in a form of ratio is used to change the units given in the data to the units desired
  2. 2. A sample of matter with definite & constant composition & distinct chemical properties.
  3. 4. A substance formed when two or more elements are chemically joined
  4. 5. The study of the chemistry of matter and the development of tools to measure properties of matter
  5. 6. The sedimentation of particles under the influence of the centrifugal force and it is used for separation of superfine suspensions.
  6. 7. The phase transition in which solid turns to liquid; can be used in extricating mixtures that contain 2 substances with different melting points
  7. 8. Occurs when the internal make-up of the matter stays the same
  8. 9. The phase transition in which a substance changes from solid to gas without ever through the liquid state
  9. 11. The digits in any measurement that are known with certainty with an additional one digit which is uncertain
  10. 13. Type of mixture whose composition varies from one position to another
  11. 14. Separating a homogeneous mixture composed of 2 substances with different boiling points
  12. 15. Has indefinite shape but definite volume
  13. 16. Branch of chemistry that studies about inorganic compounds, or compounds that don't contain a C-H bond
  14. 18. The ability/characteristic of a substance to react with other substances such as air, water, acid & base
  15. 20. Has indefinite shape and volume
  16. 21. Solid particles are allowed to settle first, then the liquid is poured into another container leaving behind the solid particles
  17. 24. Process of separating elemental metals from other particles in a mixture with the use of a magnet
  18. 26. A type of heterogeneous mixture that consists of coarse particles visible to the naked eye
  19. 30. A process of separating solid matter and fluid from a mixture with a filter medium in which only the fluid can pass
  20. 34. The phase transition in which gas turns to liquid
  21. 35. The simplest form of matter
  22. 38. Chemical property whether the substance can damage an organism or not
  23. 40. The quantity of matter in the object; determined by weighing the obect
  24. 41. Another method of separating complex mixtures; The mixture is dissolved in a fluid which carries it through a structure holding another material. The various constituents of the mixture travel at different speeds, causing them to separate.
  25. 43. Determined when a certain quantitative value is relatively close to the “true” value
  26. 45. Also known as extrinsic physical property
