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. High=speed - negatively charged electrons emitted in radiations






2. Substance that takes water from another substance






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






4. A relatively weak force of attraction between polar molecules; a component of van der Waals forces






5. A cell in which electrolysis is carried out






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






7. Chemical reaction that results in an absorption of heat






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






9. 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






10. Continuous zigzagging movement of colloidal particles in a dispersing medium - as viewed through and ultramicroscope






11. An ion that has a positive charge






12. An organic salt formed by the reaction of an alcohol with an acid






13. Referring to any substance that has basic properties






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






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






16. The process of taking up by capillary - osmotic - chemical - or solvent action - as a sponge absorbs water






17. 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






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






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






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






21. A property of a solution that depends primarily on the concentration - not the type of particles present






22. 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






23. Referring to a compound composed of two elements such as water






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






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






26. Determines how a substance will behave in a chemical reaction






27. Forms of the same element that differ in their crystalline structures






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






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 flow of a gas through a small aperture






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






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






33. Negatively charged particle - Mass is 9.109x10(-28)






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






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






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






37. Having no definite crystalline structure






38. Capable of being drawn into a thing wire






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






40. 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

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






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






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






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