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






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






3. Process of heating an organic substance - such as coal - in the absence of air to break it down into solid and volatile products






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






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






6. E=mc2 - relates mass to energy






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






8. Colloidal substance that forms a film about the particles of two immiscible liquids so that one remains suspended in the other






9. Organic compound containing the -O- group






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






11. Referring to any substance that has basic properties






12. The process whereby gases or liquids intermingle freely of their own accord






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






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






15. A unit of heat; the amount of heat needed to raise the temperature of 1 gram of water 1 degree on the celcius scale






16. Positively charged helium nuclei






17. A relatively weak force of attraction between polar molecules; a component of van der Waals forces






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






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






20. A compound whose basic structure contains the benzene ring; it usually has an odor






21. A property of a solution that depends primarily on the concentration - not the type of particles present






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






23. Nuclear reaction that releases energy because of the splitting of large nuclei into smaller ones






24. 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

26. Isotope of hydrogen - sometimes called heavy hydrogen - with an atomic weight of 2






27. The temperature at which the vapor pressure of a liquid equals the atmospheric pressure






28. Chemical reaction that results in an absorption of heat






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






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






31. The average mass of a number; bottom number on the element






32. Rod of certain metal such as cadmium - which controls the speed of the chain reaction by absorbing neutrons in a nuclear reactor






33. Usually - a strong base - such as Sodium hydroxide - potassium hydroxide






34. An organic hydroxyl compound formed by relacing one or more hydrogen atoms of a hydrocarbon with equal number of hydroxyl (OH) groups






35. Bonding accomplished through the sharing of electrons so that atoms can fill their outer shells






36. 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
