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






2. Negatively charged particle - Mass is 9.109x10(-28)






3. 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

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






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






7. A metallic oxide that forms a base when placed in water






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






9. 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






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






11. An ion that has a positive charge






12. The process of forming definitely shaped crystals when water is evaporated from a solution of the substance






13. Shows only the simplest ratio of the number and kids of atoms






14. Shorthand method of showing the changes that take place in a chemical reaction






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






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






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






18. Continuous zigzagging movement of colloidal particles in a dispersing medium - as viewed through and ultramicroscope






19. Capable of being drawn into a thing wire






20. The adhesion (in an extremely thing layer) of the molecules of gases - of dissolved substances - or of liquieds to the surfaces of solid or liquid bodies with which they come into contact






21. The point in a reversible reaction at which the forward reaction is occurring at the same rate as the opposing reaction

23. Forms of the same element that differ in their crystalline structures






24. A substance composed of elements chemically united in definite proportions by weight






25. The process of taking up by capillary - osmotic - chemical - or solvent action - as a sponge absorbs water






26. 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
