CHEMISTRY1

Across

4. particles are packed tightly together so they don't move much
6. process in which factor written in a form of ratio is used to change the units given in the data to the units desired
7. whether the undergoes combustion or not
8. also called a solution
13. occurs when a gas transforms directly into a solid
18. a process of separating the components of a suspension
21. space occupied by a substance
25. whether it will break into charged particles when in solution with water or not
26. determined when a quantitative value is relative close to the true value
29. composition varies from one position to another within the sample
30. weight of a object
32. consist of a dispersed phase or the substance dissolved or scattered and a dispersing medium or the substance in which the dispersed phase is spread
38. the ratio of the mass of an object to the volume it occupies
40. The study of the chemistry of matter and the development of tools to measure properties of matter
41. The study of carbon and its compounds
42. this makes use of a magnet which exerts magnetic force to attract metallic particles and sets them apart from a certain mixture
43. The branch of chemistry that applies physics to the study of chemistry, which commonly includes the applications of thermodynamics and quantum mechanics to chemistry
46. The study of compounds not covered by organic chemistry
47. using centrifugal force to separate the mixture
48. process of simplifying a very large number
50. composed of two or more substance combined physically in variable proportion

Down

1. whether the material is more active or less active then other members of its chemical family
2. consist of coarse particle which are visible to the naked eye
3. physical properties, those that can be affected by size and amount of samples
5. a pure substance containing two or more kind s of atom chemically combined in a definite proportion by mass
9. a matter that has a definite composition and distinct properties
10. a process of separating a homogeneous mixture composed of to substance with different boiling points
11. the consistency of the result
12. the conversion of a liquid to a gas and can occur through either evaporation or boiling
14. When a solid is converted directly into a gas without going through a liquid phase
15. the solid particles are allowed to settle first at the bottom and later, the liquid which is called supernatant is poured into another container leaving behind the solid particles
16. occurs when a gas loses energy and comes together to form a liquid
17. the particles are more loosely packed than in a solid and are able to flow around each other
19. the dissolved substance
20. whether it react with acid, base and gasses or not
22. When the substance reaches a cool enough temperature at a certain pressure, the freezing point, the liquid becomes a solid
23. The study of chemical processes that occur inside of living organisms
24. the simplest form of matter since it is composed of only one kind of atom
27. how cold or hot an object
28. When the substance reaches a certain combination of temperature and pressure, its melting point, the solid will begin to melt and turn into a liquid.
31. whether substance can be decomposed or not
33. the ability of a substance to react other substance
34. another method of separating complex mixture
35. are those that can be measured and observed without changing the composition of the substance
36. determined when a quantitative value is relative close to the true value
37. the dissolving medium
39. the study of matter and chemical reaction between substance
44. physical properties, does not depend on the size or amount of the sample
45. whether the substance can damage an organism or not
49. the particles have a great deal of space between them and have high kinetic energy
