Across
  1. 2. a substance or matter in a state in which it will expand freely to fill the whole of a container having no fixed shape and no fixed volume.
  2. 4. the quality, condition, or fact of being exact and accurate.
  3. 5. states that atoms other than hydrogen tend to form bonds until surrounded by eight valence electrons
  4. 6. the measurement or extent of something from end to end.
  5. 8. it is a branch of chemistry that deals with synthesis and behavior of inorganic and organometallic compounds.
  6. 14. a substance or object that is solid rather than liquid or fluid
  7. 16. Element that appears at the far right side of the periodic table
  8. 19. Organic compound with carbon and oxygen only
  9. 20. the quality or state of being correct or precise.
  10. 22. Horizontal row in the periodic table
  11. 24. it is a branch of chemistry that studies and uses instruments and methods used to separate identify and quantify matter.
  12. 26. a substance that flows freely but is of constant volume having a consistency like that of water or oil.
  13. 27. a metric unit of length equal to one hundredth of a meter.
  14. 28. movement of one fluid through another.
  15. 34. Composed of two or more substances combined physically in variable proportions
  16. 35. Indicates that one mole of an element has a mass in grams numerically equal to its atomic mass units
  17. 37. Elements found in the zigzag order in the periodic table
  18. 39. Mixture whose a composition varies from position to position within a sample.
  19. 44. Anything that has mass and occupies space
  20. 45. Called as solution a mixture with uniform composition.

Down
  1. 1. it is a branch of chemistry that studies the structure properties and reactions of organic compounds which contain carbon in covalent bonding. Study of structure determines their chemical composition and formula.
  2. 3. Process in which the solid particles are filtered to allow the liquid or filtrate to pass through the filter and be collected as residue
  3. 7. Group 7A elements
  4. 9. The separation of elemental metals from the mixtures
  5. 10. Separates components of mixture at different boiling points.
  6. 11. a result without the expected content
  7. 12. The amount of space occupied by a substance
  8. 13. Negatively charged subatomic particle of an atom
  9. 15. it is a branch of chemistry that studies the chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life.
  10. 17. phase change in which liquid is converted to gas
  11. 18. Positively charged subatomic particle of an atom
  12. 21. inner transition elements located in the first row of the f block in the periodic table
  13. 22. the branch of chemistry concerned with the application of the techniques and theories of physics to the study of chemical systems.
  14. 23. the fundamental unit of length in the metric system equal to 100 centimeters or approximately 39.37 inches.

  17. 30. Formed by losing and gaining of electrons between metal and nonmetal
  18. 31. a metric unit of capacity formerly defined as the volume of one kilogram of water under standard conditions now equal to 1 000 cubic centimeters
  19. 32. insert gas located at the rightmost side of the periodic table
  20. 33. the branch of science that deals with the identification of the substances of which matter is composed.
