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 liquid that will conduct and electric current






2. Determines how a substance will behave in a chemical reaction






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

7. Loss by a substance of its water of hydration on exposure to air at ordinary temperatures






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






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






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






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






12. Streams of electrons given off by the cathode of a vacuum tube






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






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






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






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






17. A cell in which electrolysis is carried out






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






19. The difference in potential between an electrode and the solution in which it is immpesed






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






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






22. Capacity to do work






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






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






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






26. The number of molecules in 1 gram-molecular volume of a substance - or the number of atoms in 1 gram-atomic mass of an element 6.02 x 10(-27)

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






28. Chemical reaction that results in the giving off of heat






29. The electrode in an electrolytic cell that is negatively charged and attracts positive ions






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






31. Having no definite crystalline structure






32. Containing no water






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






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






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






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






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






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






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






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






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






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






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






44. Separation of the ions of an ionic compound due to the action of a solvent






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






46. Absorbtion by a substance of water from the air - so that the substance becomes wet






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






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






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






50. Organic compound containing the -O- group
