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 temperature scale divided into 100 equal divisions and based on water freezing at 0 degress and boiling at 100 degrees






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






3. A chemical action in which both heat and light are given off






4. A substance composed of two or more metals - which are intimately mixed; usually made by melting the metals together






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






6. The temperature above which no gas can be liquefied - regardless of the pressure applied






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






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. To take water from a substance






10. Substance that - when added to a solution - makes changing the pH of the solution more difficule






11. A. change from gas to liquid B. the combination of molecules without water






12. Referring to any substance that has basic properties

15. A terminal of an electrolytic cell






16. A liquid that will conduct and electric current






17. A reaction in which two chemical substances exchange ions with the formation of two new compounds






18. 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






19. The layer of gasses surrounding the earth - A unit of pressure (1 atm = 760mm of Hg or torr)






20. The numerical expression of the relative strength with which the atoms of an element attract valence electrons to themselves; the higher the number - the greater the attraction






21. 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






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






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