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. Ethyl alcohol that has been poisoned in order to produce a cheaper alcohol for industrial purposes






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






3. Positively charged helium nuclei






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






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






6. Covalence in which both electrons in a pair come from the same atom






7. Process for converting atmospheric nitrogen into compounds






8. A compound derived from another compound by the removal of water; it will combine with water to form an acid (acidic anhydride) or base (basic anhydride)






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






10. Heat content of a chemical system






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






12. To take water from a substance






13. The measure of disorder in a system






14. Capacity to do work






15. Referring to a compound composed of two elements such as water






16. An instrument - invented by Toricelli in 1643 - used for measuring atmospheric pressure






17. Chemical reaction that results in the giving off of heat






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






19. Chemical reaction that results in an absorption of heat
