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. Unit for expressing the kinetic energy of subatomic particles; the energy acquired by an electron when it is accelerated by a potential difference of 1 volt






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






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






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






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






6. Positively charged helium nuclei






7. Science concerned with the compositions of substances and the changes that they undergo






8. A water solution that has an excess of hydrogen ions; an acid turns litmus paper pink or red - has a sour taste - and neutralizes bases to form salts






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






10. A compound derived from another compound by the removal of water; it will combine with water to form an acid (acidic anhydride) or base (basic anhydride)






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






12. A reaction produced during nuclear fission when at least one neutron from each fission produces another fission - so that the process becomes self sustaining without additional external energy






13. Nuclear reaction that releases energy because of the splitting of large nuclei into smaller ones






14. Rod of certain metal such as cadmium - which controls the speed of the chain reaction by absorbing neutrons in a nuclear reactor






15. A bond between atoms involving two electron pairs - unsaturated






16. Substance that - when added to a solution - makes changing the pH of the solution more difficule






17. Heat content of a chemical system






18. Top number on periodic table - The number of protons in the nucleus - The number of electrons in an atom






19. A specially treated and finely divided form of carbon - which possesses a high degree of absorbtion






20. Chemical reaction that results in an absorption of heat






21. Solid carbon dioxide






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






23. The temperature above which no gas can be liquefied - regardless of the pressure applied






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






25. The process of separation of a solution by diffusion through a semipermeable membrance






26. Breaking down of a compound into simpler substances or constituent elements






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






28. Containing no water






29. A salt formed by replacing part of the hydrogen ions of a dibasic or tribasic acid with metallic ions - Examples: NaHSO4 - NaH2PO4






30. The process whereby gases or liquids intermingle freely of their own accord






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






32. The flow of a gas through a small aperture






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






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






35. 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






36. The rapid escape of excess gas that has been dissolved into a liquid






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






38. A reaction in which two chemical substances exchange ions with the formation of two new compounds






39. Having no definite crystalline structure

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






43. Process for converting atmospheric nitrogen into compounds






44. A unit of heat; the amount of heat needed to raise the temperature of 1 gram of water 1 degree on the celcius scale






45. 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






46. An ion that has a positive charge






47. 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
