SAT Subject Test: Chemistry Vocab

Subjects : sat, science, chemistry
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Having no definite crystalline structure






2. Containing no water






3. 1/2 the distance between adjacent nuclei in the crystalline or solid phase of an element; distance from the atomic nucleus to the valence electrons






4. A nonmetallic oxide that - when placed in water - reacts to form an an acid solution






5. The union of atoms to form compounds or molecules by filling their outer shells of electonrs. This can be done through giving and taking electrons (ionic) or by sharing electrons






6. The adhesion (in an extremely thing layer) of the molecules of gases - of dissolved substances - or of liquieds to the surfaces of solid or liquid bodies with which they come into contact






7. One of the building blacks matter is composed of - only one type of atom; cannot be further decomposed






8. The highest temperature at which water vapor condenses out of the air






9. The smallest particle of an element that retains the properties of that element and can enter into a chemical reaction






10. Shows only the simplest ratio of the number and kids of atoms






11. A substituent obtained from a saturated hydrocarbon by removing one hydrogen atom -Examples: methyl(CH3) ethyl(C2H5)






12. Absorbtion by a substance of water from the air - so that the substance becomes wet






13. A chance that alters the atomic structures of the substances involved and results in different properties






14. Positively charged helium nuclei






15. The process by which suspended matter is removed from a liquid by passing the liquid through a porous material






16. A change by which an element takes the place of another element in a compound






17. A substance used to remove the excess chlorine in the bleaching process






18. The electrode in an electrolytic cell that is negatively charged and attracts positive ions






19. Residual radioactivity from an atmospheric nuclear test - eventually settles on the surface of the earth






20. The point in a reversible reaction at which the forward reaction is occurring at the same rate as the opposing reaction






21. A substance composed of elements chemically united in definite proportions by weight






22. Colloidal substance that forms a film about the particles of two immiscible liquids so that one remains suspended in the other






23. A substance composed of two or more metals - which are intimately mixed; usually made by melting the metals together






24. Referring to any substance that has basic properties






25. The series of radioactive elements starting with actinium - No. 89 - and ending with lawrencium - No. 103






26. A liquid that will conduct and electric current






27. A metallic oxide that forms a base when placed in water






28. A. change from gas to liquid B. the combination of molecules without water






29. A chemical action in which both heat and light are given off






30. The difference in potential between an electrode and the solution in which it is immpesed






31. Capable of being drawn into a thing wire






32. High=speed - negatively charged electrons emitted in radiations






33. Process for converting atmospheric nitrogen into compounds






34. The minimum energy necessary to start a reaction






35. Temperature scale that has 32 as freezing point and 212 as boiling point






36. The average mass of a number; bottom number on the element






37. The process of separating the ions in a compound by means of electrically charged poles

43. The layer of gasses surrounding the earth - A unit of pressure (1 atm = 760mm of Hg or torr)






44. An organic hydroxyl compound formed by relacing one or more hydrogen atoms of a hydrocarbon with equal number of hydroxyl (OH) groups






45. Particles larger than those found in a solution but smaller than those in a suspension
