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 compound such as CH3NH2 - derived from ammonia by substituting one or more hydro-carbon radicals for hydrogen atoms






2. The smallest amount of fissionable material that will sustain a chain reaction






3. A change by which an element takes the place of another element in a compound






4. Depositing a thin layer of metallic element on the surface of another metal by electrolysis

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






7. A substance that speeds up or slows down a reaction without being permanently changed itself






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






9. A salt formed by replacing part of the hydrogen ions of a dibasic or tribasic acid with metallic ions - Examples: NaHSO4 - NaH2PO4






10. One of the "building blocks" of proteins; contains one or more NH2- groups that have replaced the same number of hydrogen atoms in an organic acid






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






12. Top number on periodic table - The number of protons in the nucleus - The number of electrons in an atom






13. 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






14. 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






15. Science concerned with the compositions of substances and the changes that they undergo






16. A substituent obtained from a saturated hydrocarbon by removing one hydrogen atom -Examples: methyl(CH3) ethyl(C2H5)






17. The process by which suspended matter is removed from a liquid by passing the liquid through a porous material
