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






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






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






4. E=mc2 - relates mass to energy






5. A nonmetallic oxide that - when placed in water - reacts to form an an acid solution






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






7. Capacity to do work






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






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






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






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






12. A chance that alters the atomic structures of the substances involved and results in different properties






13. High=speed - negatively charged electrons emitted in radiations






14. The process of separation of a solution by diffusion through a semipermeable membrance






15. A device used to accelerate charged particles to high energies for bombarding the nuclei of atoms






16. A specially treated and finely divided form of carbon - which possesses a high degree of absorbtion






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






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






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






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






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






22. Positively charged helium nuclei






23. Organic compound containing the -O- group






24. Heat content of a chemical system






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






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






27. 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






28. The breaking down of a compound into two or more simpler substances






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






30. 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






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






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






33. One of the building blacks matter is composed of - only one type of atom; cannot be further decomposed






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






35. An ion that has a positive charge






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






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






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






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






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






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






42. Chemical reaction between an alcohol and an acid - in which an ester is formed






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






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






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






46. To take water from a substance






47. Process for converting atmospheric nitrogen into compounds






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






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






50. Solid carbon dioxide
