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 smallest particle of an element that retains the properties of that element and can enter into a chemical reaction






2. Residual radioactivity from an atmospheric nuclear test - eventually settles on the surface of the earth






3. 1/2 the distance between adjacent nuclei in the crystalline or solid phase of an element; distance from the atomic nucleus to the valence electrons






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






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






6. 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






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






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






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






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






11. The use of radioactive carbon-14 to estimate the ages of ancient materials - such as archaeological or paleontological specimens






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






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






14. 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






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






16. Nuclear reactor in which more fissionable material is produced than is used up during operation






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






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






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






20. The series of radioactive elements starting with actinium - No. 89 - and ending with lawrencium - No. 103






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






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






23. The union of atoms to form compounds or molecules by filling their outer shells of electonrs. This can be done through giving and taking electrons (ionic) or by sharing electrons






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






25. Covalence in which both electrons in a pair come from the same atom






26. Referring to a compound composed of two elements such as water






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






28. Referring to any substance that has basic properties






29. 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






30. An instrument used to measure the amount of heat liberated or absorbed during a change






31. The energy needed to break a chemical bond and form a neutral atom






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

34. Containing no water






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






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






37. The mass per unit volume of a substance; mathematical formula D=m/V
