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.

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






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






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






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






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






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






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






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

37. Chemical reaction that results in an absorption of heat






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






39. The process of first vaporizing a liquid and then condensing the vapor back into a liquid - leaving behind the nonvolatile impurities






40. 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
