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. A water wolution that contains an excess of hydroxide ions; a proton acceptor; a base turns litmus paper blue and neutralizes acids to form salts

4. The highest temperature at which water vapor condenses out of the air






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






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






7. Organic compound formed by dehydrating oxidized alcohol; contains the characteristic - CHO group






8. Streams of electrons given off by the cathode of a vacuum tube






9. A bond between atoms involving two electron pairs - unsaturated






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






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






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






13. Graduated glass tube into which gases are placed and subjected to an electric spark; measures the individual volumes of combining gases






14. A device used to accelerate charged particles to high energies for bombarding the nuclei of atoms






15. Temperature scale that has 32 as freezing point and 212 as boiling point






16. Unit for expressing the kinetic energy of subatomic particles; the energy acquired by an electron when it is accelerated by a potential difference of 1 volt






17. Temperature measured on the absolute scale - which has its origin at absolute zero






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






19. A nonmetallic oxide that - when placed in water - reacts to form an an acid solution
