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






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

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






23. The temperature at which the vapor pressure of a liquid equals the atmospheric pressure






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






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






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