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






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






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






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






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

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






9. Positively charged helium nuclei






10. 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






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






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






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






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






15. Organic compound formed by dehydrating oxidized alcohol; contains the characteristic - CHO group






16. 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






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






18. Solid carbon dioxide






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






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






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






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

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






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






29. Chemical reaction that results in an absorption of heat






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






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






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






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






34. 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

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






37. 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
