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.

26. The energy needed to break a chemical bond and form a neutral atom






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






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






29. The rapid escape of excess gas that has been dissolved into a liquid






30. Substance that takes water from another substance






31. Capacity to do work
