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.

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






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






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






24. Shorthand method of showing the changes that take place in a chemical reaction






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






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






27. 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






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






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






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






31. 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
