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. Chemical reaction that results in the giving off of heat






2. The mass per unit volume of a substance; mathematical formula D=m/V






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






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






5. A compound whose basic structure contains the benzene ring; it usually has an odor






6. The measure of disorder in a system






7. Streams of electrons given off by the cathode of a vacuum tube






8. An ion or particle that has a negative charge and thus is attracted to a positively charged anode






9. Ethyl alcohol that has been poisoned in order to produce a cheaper alcohol for industrial purposes






10. Covalence in which both electrons in a pair come from the same atom






11. A water wolution that contains an excess of hydroxide ions; a proton acceptor; a base turns litmus paper blue and neutralizes acids to form salts






12. Loss by a substance of its water of hydration on exposure to air at ordinary temperatures






13. Having definite molecular or ionic structure






14. Graduated glass tube into which gases are placed and subjected to an electric spark; measures the individual volumes of combining gases






15. Referring to any substance that has basic properties






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






17. 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






18. The temperature at which the vapor pressure of a liquid equals the atmospheric pressure






19. The process of forming definitely shaped crystals when water is evaporated from a solution of the substance






20. Chemical reaction between an alcohol and an acid - in which an ester is formed






21. 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






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






23. Process for converting atmospheric nitrogen into compounds






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






25. Nuclear reactor in which more fissionable material is produced than is used up during operation






26. An instrument - invented by Toricelli in 1643 - used for measuring atmospheric pressure






27. Usually - a strong base - such as Sodium hydroxide - potassium hydroxide






28. An ion that has a positive charge






29. A liquid that will conduct and electric current






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






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






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






33. One of the "building blocks" of proteins; contains one or more NH2- groups that have replaced the same number of hydrogen atoms in an organic acid






34. Substance that takes water from another substance






35. The use of radioactive carbon-14 to estimate the ages of ancient materials - such as archaeological or paleontological specimens






36. Containing no water






37. The smallest amount of fissionable material that will sustain a chain reaction






38. The number of molecules in 1 gram-molecular volume of a substance - or the number of atoms in 1 gram-atomic mass of an element 6.02 x 10(-27)

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






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






41. A compound such as CH3NH2 - derived from ammonia by substituting one or more hydro-carbon radicals for hydrogen atoms






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






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






44. Separation of the ions of an ionic compound due to the action of a solvent






45. A device used to accelerate charged particles to high energies for bombarding the nuclei of atoms






46. An instrument used to measure the amount of heat liberated or absorbed during a change






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






48. Suspension of fine particles or droplets of one liquid in another - the two liquids being immiscible in each other; surrounded by an emulsifying agent






49. Referring to a hydroxide that may have either acidic or basic properties - depending on the substance with which it reacts






50. A substance that speeds up or slows down a reaction without being permanently changed itself
