  8. 19. Study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds.
  9. 24. BOTH SHAPE AND VOLUME, GASES ARE INDEFINITE. THINK OF IT THAT IF WE CONTAIN IT, IT CAN’T BE HELD ON ONE PLACE AS IT MAY BE ABLE TO ESCAPE ON RIGID SPACES, AND THAT IT IS ABLE TO EXPAND THOROUGHLY WHICH CAN’T BE EASILY MEASURED.
  10. 27. IN TERMS OF SHAPE AND VOLUME, IT IS INDEFINITE AND DEFINITE, RESPECTIVELY.
  11. 28. IN TERMS OF SHAPE AND VOLUME, IT IS DEFINITE, AS IT HAS THE ABILITY TO RETAIN ITSELF AS IT IS BEFORE, THUS BEING IN A FIXED MANNER.
  12. 29. Negatively Charged Ions
  13. 32. Experiment performed by Robert Millikan and Harvey Fletcher in 1909 to measure the charge of the electron.
  14. 34. is also the study of matter's composition, structure, and properties.
  15. 35. an ion with a negative electrical charge.
  16. 37. Any of the participants present at the start of a chemical reaction.
  17. 39. simplest form of matter since it’s composed of only one kind of atom.
  18. 40. When energy is transferred to dry ice, the solid carbon dioxide does not melt to liquid carbon dioxide.
  19. 42. A conversion factor changes one unit to a new unit.
  20. 45. - substance made by melting together two or more elements, at least one of which must be a metal.
  21. 47. This is something that was forced to mixed, and doesn’t completely mix.
  22. 49. relatively uniform in comparison.
  23. 51. Study of chemistry of life, living organism.
  24. 52. An early experimental electrical discharge tube.
  25. 53. Analysis: A method of converting from one unit to another. It is also sometimes called unit conversion.
Down
  1. 1. Positively Charged Ions
  2. 3. Is an element that doesn’t have the characteristics of metal, such as the ability to conduct heat or electricity, luster, or flexibility.
  3. 4. As for the melting or liquefaction process, an external energy takes place to the ice which is being driven by a drastic change in temperature.
  4. 6. is the number of protons in an element.
  5. 8. are various forms of an element that have the same number of protons but a different number of neutrons.
  6. 9. Study of chemistry combined with physics, equilibrium (derivatives).
  7. 10. Study of elements and ionically compounds except carbon and hydrogen.
  8. 12. carbon containing compound that is bonded with hydrogen. Can be bonded with oxygen (protein)
  9. 13. a chemical species that accepts electrons or donate protons or hydrogen ions.
  10. 14. In the first place, water's structure of particles is not too compressed, so if you freeze it, the particles lose its movement capability and transposes to friction, for it to move closer and stack with each other, then it's frozen.
  11. 15. A matter that has definite composition and distinct properties.
  12. 20. A chemical compound that lacks carbon-hydrogen bonds. It is any substance in which two or more chemical elements (usually other than carbon) are combined.
  13. 21. analysis of the composition, studies and uses instruments and methods used to separate, identify, and quantify matter.
  14. 22. substances cannot be separated into any other kinds of matter while a mixture is combination of two or more substances.
  15. 23. are made up of atoms all having the same number of protons.
  16. 25. Is a Chemical element that exhibits some properties of metals and some non-metals.
  17. 26. Everything is made up of.
  18. 30. Elements that readily forms positive ions (cations) and has metallic bonds.
  19. 31. smallest component of an element,
  20. 33. A chemical substance formed as a result of a chemical reaction.
  21. 36. Mixture Mixture whose composition varies from one position to another within the sample is considered as heterogenous.
